Can someone check my answers please!!!
Simplify (tan ^2 theta csc^2 theta-1)/(tan^2 theta).
My answer: 1
Simplify ((cos x)/(sec x-1)) + ((cos x) /(sec x +1)
My answer: 2cot^2 x
Find a numerical value of one trigonometric function of x if (tan x/cot x )– (sec x/cos x ) = (2/csc x).
My answer: sin x= -1/2
I agree with all 3 results.
