sinA + cosA > 1 where A is 0< A < 90 in ABC triangle

prove that sinA-cosA+1/sinA+cosA-1=1/secA-tanA

Prove : (sinA-cosA+1)/(sinA+cosA-1) = (1+sinA)/cosA

if 8 tan Q=15 then sinA-cosA=?

if sinA+cosA=1/5, then a value of tanA/2 satisfies which of the equation? a. 2x^2-x-1 b.x^2-2x-3=0...

Sina+cosa=root over cosA

prove that :cosA-sinA+1/cosA+sinA-1=cosecA+cotA

SinA+ cosA=17/3 find sinA-cosA

1-cosA+sinA DIVIDED BY 1+cosA+sinA

If cosA + sinA= root2 cosA Show that cosA - sinA= root2 sinA
