Question

tan theta + cot theta = sec theta csc theta

Answer 1

tan(x) +cot(x) = sin(x)/cos(x) + cos(x)/sin(x) = (sin^2(x) + cos^2(x))/(sin(x)cos(x))
=1/(cos(x)*sin(x)) = 1/sinx * 1/cosx = csc(x)*sec(x)

Answer 2

(1- cos^2x) (1+ cot^2x)=1

Answer 3

?

Answer 4

is the 1st problem Lhs = Rhs ?

Answer 5

That's #2 another problem im having troubles with .

Answer 6

yes the first problem lhs =rhs
close this and ask another
