Use basic identities to simplify the expression cos²theta /sin² theta+ csc theta sin theta

Phantasy [73]

For convenience sake, I will be omitting the arguments of the trig functions.

cos²/sin² + (cos)/(sin)
= cos²/sin² + (cos sin)/sin²
= (cos² + cos sin)/(sin²)

Which of the following is a valid exclusion for the algebraic fraction 8ab^2x/4a^2b-8ab^2

Molodets [167]

Answer:

a ≠ 2b

Step-by-step explanation:

The given expression is

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}}$

$=\frac{8ab^{2}x}{4ab(a-2b)}$

Simplifying it, we have

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}} = \frac{bx}{a-2b}$

For the above fraction to exist, the denominator must not be equal to zero.

i.e, a-2b ≠ 0

=> a≠2b

∴ The algebraic fraction exists when a≠2b.
