Answer #1
Your equations contain only trig operators but they have no arguments
e.g. sin^2 is meaningless, it has to be something like sin^2Ø or sin^2x
Your expression is as meaningless as trying to evaluate
5 + √
anyway .....
for sin^2+tan^2=sec^2-cos^2
LS = sin^2x + sin^2x/cos^2x
= (sin^2x cos^2x + sin^2x)/cos^2x
= sin^2x(cos^2x + 1)/cos^2x
= (1 - cos^2x)(1+cos^2x)/cos^2x
= (1 - cos^4x)/cos^2x
RS = 1/cos^2x - cos^2x
= (1 - cos^4 x)/cos^2x
= LS
the 2nd:
LS = sin^2x(1/cos^2x) + sin^2x
= tan^2x + sin^2x
= RS

How would you establish this identity: (1+sec(beta))/(sec(beta))=(sin^2(beta))/(1-cos(beta)) on the right, sin^2 = 1-cos^2, that factor to 1-cos * `1+cos, then the denominator makes the entire right side 1+cosB which is 1+1/sec which is 1/sec (sec+1)
If α and β are two angles in Quadrant II such that tan α= -1/2 and tan β = -2/3, find cos(α+β) Work: cos(α+β) = [ 1 - (tan α)(tan β) ] / [ 1 + (tan α)(tan β)] cos(α+β) = [ 1 - (-1/2)(
verify that each of the following is an identity: 1) cos x/ 1-sin^2x= sec x 2) sec x/sin x - sin x/cos x = cot x 3) 1+tan^2ø/ cos ^2ø = sec^4 ø I really need ur help :) thank u so much
