Simplify and write the trigonometric expression in terms of sine and cosine: tan u + cot u = 1/f(u)

The requested trigonometric expression in terms of sine and cosine is;

We must remember,

Therefore we have;

sin(u)/cos(u) + cos(u)/sin(u) = 1/f(u)

By Cross-product; we have;

Therefore, the required function, f(u) in terms of sin u and cos u is as represented above.

we have the expression as;

1/sin u cos u

Step-by-step explanation:

tan u = sin u/cos u

cot u = cos u/sin u

Thus;

sin u/cos u + cos u/sin u

The lcm is sin u cos u

Thus, we have that;

(sin^2 u + cos^2 u)/sin u cos u

But ; sin^2 u + cos^2 u = 1

so we have ;

1/sin u cos u

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
