Question

Integral of sin(2x)/cos(x)?

Answer 1

what is another way of writing sin(2x)?

Answer 2

this is the reason you learn trigonometry/pre calculus ....

Answer 3

Wait, does this use the double angle formula?

Answer 4

it might ....

Answer 5

you can always use that

Answer 6

is there a simpler way?

Answer 7

or a different way altogether

Answer 8

trig is never simple

Answer 9

I'm just curious as to the options I have.

Answer 10

using the wolf lol

Answer 11

use an abacus

Answer 12

sin(a+b) = sin(a)cos(b) + sin(b)cos(a)

if a=b

sin(x+x) = sin(x)cos(x) + sin(x)cos(x)

sin(2x) = 2sin(x)cos(x)

Answer 13

thank you, that's helpful

Answer 14

I got it.
