Can someone please help me do this problem? That would be great! Simplify the expression: sin theta + cos theta * cot theta I'll use A for theta. Cot A = sin A / cos A Therefore: sin A + (cos A * sin A / cos A) = sin A + sin A = 2

Verify the identity. (csc(2x)  sin(2x))/cot(2x)=cos(2x) =csc(2x)/cot(2x)  sin(2x)/cot(2x) =csc(2x)/cot(2x)  cos(2x) Is this correct so far? If so then how would I continue? I got stuck on this part...

1)if the graph of f(x)=cotx is transformed by a horizontal shrink of 1/4 and a horizontal shift left pi, the result is the graph of: a) g(x)= cot[1/4(xpi)] b) g(x)=cot[1/4(x+pi)] c) g(x)=cot[4(xpi)] d) g(x)=cot[4(x+pi)] e)
