The semi-vertical angle of an ice-cream cone is 22° and its height is 13cm. Find the diameter of its largest cross section.

why cant i simplfy tan^2csc^2-1 to tan^2cot^2 ?

I have managed to reach so far y=90 - x Sec(90-x)-tan(90-x)=csc(X)-cot(X)= 1-cos(X)/sin(X)

If Sin∅+cos∅=√2,then evaluate:tan∅+cot∅

I need help with figuring out how to answer these questions the choices for answers are 1. 93 2. 98 3. 102 4. 115

If tan theta < 0 and sin theta = 8/17, what are the exact values of the other two trig ratios? What is the reference angle and terminal angle?

I was playing around with tan(4*arctan(x))=2 and noticed x^2-x-1 and x^4-5*x^2+5 were in the solutions. It just seemed strange to me. Do identities work on these? Why is it adding/subtracting...

The answer cannot include sin or pie since the homework is not letting me use what I came up with... cos(13pi/60-7pi/60) = cos(6pi/60) = cos pi/10?
