We have a really easy way to determine the period of the sine function. If we have a sine function of the form f(x) = Asin(Bx + C) + D, then the period of the function is 2π / |B|.
What is the period of a sine function?
The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.
How do I find the period of a function?
We can always calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin (B a – c) and y = A cos ( B a – c ) is equal to 2πB radians. The reciprocal of the period of a function is equal to its frequency.
What is the period of sine and cosine?
The basic sine and cosine functions have a period of 2π. The function sin x is odd, so its graph is symmetric about the origin. The function cos x is even, so its graph is symmetric about the y-axis.
Does sin repeat every 180?
It repeats itself every 180 degrees. Maximum value = +∞
What is the period of sin 4x cos 4x?
So π/2 is the period of the function.
Why is the period of tan 180?
tan θ = 1 when θ = 45˚ and 225˚. tan θ = –1 when θ = 135˚ and 315˚. As the point P moves round the unit circle in either the clockwise or anticlockwise direction, the tangent curve above repeats itself for every interval of 180˚. Its period is 180˚.
What is the interval of a sine graph?
This interval is generally 2π radians (or 360º) for the sine and cosine curves. This sine curve, y = sin x, completes 1 cycle in the interval from 0 to 2π radians.
What is the period of sin2x?
The period of sin 2x would be 2π2 that is π or 180 degrees.
What is sin 4x period?
This should be enough to tell you that sin4x=38−12cos2x+18cos4x has period π.
How do you find the period of Cos 4x?
In this case, we have to divide the normal period by B in order to find the period. For your specific question, y=cos4x , the amplitude would be 1 and the period would be 2π4 , or π2 . NOTE: I wanted to mention to be careful when finding the period of tangent, as the normal period of tangent is π .
How do you find the value of sin 30?
The value of sin 30 degrees can be calculated by constructing an angle of 30° with the x-axis, and then finding the coordinates of the corresponding point (0.866, 0.5) on the unit circle. The value of sin 30° is equal to the y-coordinate (0.5). ∴ sin 30° = 0.5.
How do you find sin 25 without a calculator?
How to Find the Value of Sin 25 Degrees? The value of sin 25 degrees can be calculated by constructing an angle of 25° with the x-axis, and then finding the coordinates of the corresponding point (0.9063, 0.4226) on the unit circle. The value of sin 25° is equal to the y-coordinate (0.4226). ∴ sin 25° = 0.4226.
What is the period of sine cosine and tangent?
The period of the sine and cosine functions is 2π (pi) radians or 360 degrees. For the tangent function, the period is π radians or 180 degrees.
Why period of tan is pi?
The period of the tangent function is π because the graph repeats itself on intervals of kπ where k is a constant.

What is the period of sin3x cos3x?
Statement 1: Period of sin3x+cos3x is 2π
What is the period of cos2x?
Period would be 2π2 or π .
What is the period of sin 30?
The value of sin 30 degrees is 0.5. Sin 30 is also written as sin π/6, in radians. The trigonometric function also called as an angle function relates the angles of a triangle to the length of its sides.
How do you find sin 20?
How to Find the Value of Sin 20 Degrees? The value of sin 20 degrees can be calculated by constructing an angle of 20° with the x-axis, and then finding the coordinates of the corresponding point (0.9397, 0.342) on the unit circle. The value of sin 20° is equal to the y-coordinate (0.342). ∴ sin 20° = 0.342.
How do you find the value of sin 15?
The value of sin 15° can be found by making an angle of 15° with the x-axis and then finding the coordinates of the corresponding point (0.9659, 0.2588) on the unit circle. The value of sin 15° is equal to the y-coordinate (0.2588). Thus, sin 15° = 0.2588.
