With is the integral of (9(sinx+cosx))/sin(2x)

• Calculus -

9(sinx + cosx)/sin2x
= 9( sinx/(2sinxcosx) + cosx/(2sinxcosx)
= (9/2)(1/cosx + 1/sinx)
= (9/2) (secx + cscs)

can you take it from there?
(the integrals of secx and cscx should be part of your repertoire of basic integrals)

That's the same as the integral of sin^2 x dx. Use integration by parts. Let sin x = u and sin x dx = dv v = -cos x du = cos x dx The integral is u v - integral of v du = -sinx cosx + integral of cos^2 dx which can be rewritten integral …

Prove: (tanx)(sinx) / (tanx) + (sinx) = (tanx) - (sinx) / (tanx)(sinx) What I have so far: L.S. = (sinx / cosx) sinx / (sinx / cosx) + sinx = (sin^2x / cosx) / (sinx + (sinx) (cosx) / cosx) = (sin^2x / cosx) / (cosx / sinx + sinxcosx)
