Question

how to integrate sin^2x-cos^2x?

Answer 1

isn't this something like \(\cos(2x)\) ?

Answer 2

or maybe its negative, one or the other

Answer 3

integrate (sin^2(x)-cos^2(x)) dx ?

Answer 4

In solving an equation for x, you distribute a –4 on one side of the equation. What needs to be done to the other side of the equation?
A.
multiply by 4
B.
add –4
C.
subtract 4
D.
nothing

Answer 5

@nincompoop yes

Answer 6

\[-\int\cos(2x)dx\]

Answer 7

since \(\cos(2x)=\cos^2(x)-\sin^2(x)\)
then a simple \(u\) sub will do it

Answer 8

Yeah, use satellite's suggestion.
