Sin square 10 + sin square 80 / sec square 20 - cot square 70 – InterviewSolution

1.

Sin square 10 + sin square 80 / sec square 20 - cot square 70

Answer»

Answer:

SIN square 10+sin square(90-10)/SEC SQUARE20-cotsquare(90-20)

sin square 10+ cos square 10/sec square20 -tan square 20

(sin([email protected])[email protected])

cot([email protected])= [email protected]

sin [email protected]+cos square @=1

sec [email protected] [email protected]=1

sin square 10+cos square 10/ sec square 20-tan square 20=1/1=1
