Question

how can i prove that cot x sec x= cscx

Answer 1

I recommend you convert everything over to expressions in terms of sine and cosine first

Answer 2

cot = cos/sin

sec = 1/cos

csc = 1/sin

Answer 3

i did that but i am still lost

Answer 4

on the left side, what cancels?

Answer 5

\[csc(x)=\frac{1}{sin(x)}\]

Answer 6

\[cot(x)*sec(x)=\frac{cos(x)}{sin(x)}*\frac{1}{cos(x)}\]

Answer 7

can you explain how that works

Answer 8

never mind i got it...thanks!
