cot0(theta) = 1/tan0(theta)

2)For all 0(theta) prove:

a)cos(t) = 1/sec0(theta)

b. sec(t) = 1/cos0(theta)

- help help helpppp--math -
**visoth**, Monday, April 30, 2012 at 3:45pmare you saying for one you are trying to prove that cot theta = 1/tan theta? if so (imma change theta to x so it doesnt become a mess of words)

cotx becomes cos x/ sin x

so you have (cosx/sinx)= 1/tan x

mutiply both side by tan x giving you

(tanx) times (cosx/sinx)=1

tan x becomes sinx/cosx which will cancel out giving you 1=1
