Question

please solve - "If sin A + cos A = root 2 then evaluate : tan A + cot A"

Answer 1

heya,,,

sinA+cosA =√2


squaring on both sides

(sinA+cosA)^2=(√2)^2

sin^2A+cos^A+2sinA*cosA=2

2sinA*cosa=2-1

sinA*cosA=1/2------_1】

now ) putting on ur question
tanA+cotA

=)sinA/cosA+cosA/sinA

=)sin^2A+cos^2A/sinA*cosA

=)1/1/2 from 1)

now, it's 2 Ans.

hope it help you.
