Question

can 2(1-sin(theta)) be the same as 2-sin 2(theta)

Answer 1

Nope, the 2 must be "on" the sin, not inside it. If you put it inside you change the frequency of the sin-wave.

Answer 2

For example, the period of \(\sin(2\theta)\) is \(\pi\), while the period of the usual \(\sin\theta\) is \(2\pi\).

Answer 3

so when u distribute the 2 is it going to be 2-2sin(theta)

Answer 4

Yes, that would be right!

Answer 5

thanks

Answer 6

how do you integrate \[\cos(\theta)\sin(\theta)\]
