Quick Math Question

[jessicak]

I am doing an Integral problem and I am stuck. I need to know what the trig identity for sin2x is. Thanks

 

[Heisenberg]

2 *sin(x)*cos(x)

 

[jessicak]

thanks

people have started replacing textbooks with ATOT, scary

yup, Heisenberg isn't uncertain about that principle.

If you are doing the integral of sin(2x) then it is just -cos(2x)/2. No need to use trig identity

 

[Syringer]

I'm guessing it's only part of the problem to know the identity.

its not just sin2x...there's other stuff too and I have to use usub to cancel stuff

Yeah, tell me about it.

I miss calculus. 🙁

you're nuts.

i'm a math student and i know you're nuts.

since 3 years ago when i switched out of chemistry.

Which is why I switched over to the actuarial science major in place of math ed. 😛

I think the real problems come when they stop calling it calculus, and they start calling it analysis.. ie.. real analysis..

i have my functional analysis midterm next week.

Your answer 😛 😉

BTW: This is my standard response to ALL math threads. 😉

A girl. If you ever step away from your computer, you might discover this on your own, little one.
