If I am reading the equation correctly, I do not believe it has a solution.

How can csc^2-cot^2 = 1?

Softa [21]

ANSWER

By simplifying the left hand side using the Pythagorean Identity.

EXPLANATION

The given identity is

$\csc^{2} (x) - \cot^{2} (x) = 1$

Take the left hand side and simplify to get the right hand side.

$\csc^{2} (x) - \cot^{2} (x) = \frac{1}{\sin^{2} (x)} - \frac{ \cos^{2} (x)}{\sin^{2} (x)}$

Collect LCM for the denominators.

$\csc^{2} (x) - \cot^{2} (x) = \frac{1 - \cos^{2} (x)}{\sin^{2} (x)}$

Recall the Pythagorean Identity.

$\cos^{2} (x) + \sin^{2} (x) = 1$

This implies that:

$1 - \cos^{2} (x) = \sin^{2} (x)$

We substitute this to get,

$\csc^{2} (x) - \cot^{2} (x) = \frac{\sin^{2} (x)}{\sin^{2} (x)}$

$\csc^{2} (x) - \cot^{2} (x) = 1$

the blue dotted line means the parent function was shifted 2 units down

so the graph is g(x) = (1/3)^x-2

Answer would be A.

Multiply. <br> (−23) (16) <br> Enter your answer as a fraction, in simplified form, in the box.

kkurt [141]

Step-by-step explanation:

(-2/3 )x (1/6)

Cross Multiply:

$\frac{2}{3} . \frac{1}{6} \\$ .... so the 2 and 6 would become 1 and 3

$\frac{1}{3} .\frac{1}{3}$ ..... Like that

$\frac{1}{9}$ ..... (3x3=9)

-1/9 .... Answer

Hope this helps!!
