How do you Solve Integration of sin2 x?

Answer 1

Here one variable x so....

CODE:

>> syms x

>> int(sin(2*x))% here int is the command

sin(x)^2 - 1/2

Added:

---------------------------

What???????

int[sin2(x)] dx

= (1/2)X - (1/4)sin2X + C

==================

That " answer " above ' added ' is left to show what not to do when integrating this function. This is a standard integration formula of this trig function in the bold.
