Is cos2x equal to 2cosx?
Solution. cos2x and 2cosx and entirely different terms. 2cos x is twice the cosine of angle x. … cos2x is the cosine of angle 2x.
Is 2 sin the same as sin2?
2sinx is twice the trigonometric function sinx whereas 2x in sin2x represents angle. 2sinx is 2 times sinx, where ‘x’ is the angle. Whereas, in Sin(2x) , ‘2x’ is the angle.
Is sin2x the same as sin2x?
Nope, those are the same. As long as you have the parentheses around the sin2x, the whole thing is squared. In a calculator, that is how you would put it if you wanted to take the sine of the angle 2x, then square the result.
