Question

prove these both to be right

(sinx)/(1-cosx)+ (sinx)/(1+cosx) = 2 csc x

- tan2x + sec2x = 1

anonymous · Answer

i actually have to make the right side match the left side
and its tan^2x

anonymous · Answer

These can be "trivially" true, like "x = x" or usefully true, such as the Pythagorean Theorem's "a2 + b2 = c2" for right triangles. ... sec(x) = 1/cos(x), csc(x) ... sin2(t) + cos2(t) = 1 tan2(t) + 1 = sec2(t) 1 + cot2(t) = csc2(t) ...

anonymous · Answer

rify each trigonometric equation by substituting identities to match the right hand side ... cot x + 2 tan x + tan3x (sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x 1 + sec2x sin2x = sec2x [(sin(x))/(1-cos(x))]+[(sin(x))/(1+cos(x))]=2csc(x) - tan2x + sec2x = 1 ...

yeah i have done a few of these so far but i have gotten stuck. can you help?

anonymous · Answer

Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation. These are the directions on the sheet
