simplify sin7x-sin3x as a product of trig functions.

given (e^x)sin3x = Im((e^x)(e^i3x)) Integrate (e^x)sin3x.dx You can just take the imaginary part of...

If (e^x)(sin3x)=Im ((e^x)(e^i3x)) integrate (e^x)(sin3x) I get the answer(e^x)(cos3x-3sin3x) +...

how do you find sin7x/4x when lim x goes to 0 the answer is 7/4

prove that 5x - 7 - sin3x = 0 has at least one zero and prove that it has exactly one real zero....

Intergrate sin3x dx

sin3x−sinx=0

Please help me solve sin3x=cos(5x+10°)

Show that (sin7x+sinx)- 2sin2xcos3x= 4cos²3xsinx

Limitx--->0 sin7x/5x

Prove that cos7x+cos5x/sin7x-sin5x=cotx
