would it be: (sin^2x) x (1/sinx) = sin^2x/sinx (sin^2x/sinx) x (1/cosx) = (sin^2x)/(sinx cosx)?

there's a few... Write each expression as a single trigonometric ratio or as the number 1. 1) sint+(cott)(cost) 2) (sec x)(sin^2x)(csc x) For number one I went like this: sin t + ((1/cot)(cos/1)) sin t + (cos t/cot t) sin t + (cos t/1)( sin t/cos x) (sin t cos t)/1 + (sin t cot...

I got it, Thank you!

I think I can I didnt know that before, I will try to work it out now!

Urk, I thought that because in my third step on the left I had (cos^2A) and (-cos ^2A), that they would cancel...?

Prove the following identities: (cos A = cos B)^2 + (sin A + sin B)^2 = 2[1+cos(A-B)] I'm really a mess at this stuff. I missed a few important days and fell behind, so I don't reeeally know what to do when things start getting squared and whatnot., but I tried! :bugeye: Left Side...
