Question

HEY ... FRIENDZ..

HERE'S THE QUESTION OF MATHS .... TRIGNOMETRY.

Answer 1

√(sec²+cot²)

√(1+tan²+1+cot ²).......as 1+tan²=sec² and 1+cot²=cosec²

√(tan²+cot²+2)

√(tan²+cot²+2×cot×tan).....as tan=1/cot

now (a+b)²=a²+b²+2ab

so √{tan+cot}²

= tan+cot

=RHS

hence proved

Answer 2

hey mate,.

here is the answer
