Question

State true or false-if true than prove--
tan1°*tan89°=tan2°*tan88°

Answer 1

mate here is your answer

tan1°=cot(90°-1°)------------{ by formula}

and

tan2°=cot(90°-2°)

now by putting there values we get,

cot(90°-1°)*tan89°=cot(90°-2°)*tan88°

cot89°*tan89°=cot88°*tan88°

1=1

LHS=RHS

HENCE PROVED
