Please simplify the following trigonometric identity.

lesya692 [45]

<u>Examining the question:</u>

We are given the expression:

$\frac{1}{Sec(\alpha)-Tan(\alpha)}$

We know from Basic trigonometry that:

$Sec(\alpha) = \frac{1}{Cos(\alpha)}$

$Tan(\alpha) = \frac{Sin(\alpha)}{Cos(\alpha)}$

<u>Simplifying the expression:</u>

Replacing these values in the given expression, we get:

$\frac{1}{\frac{1}{Cos(\alpha)} -\frac{Sin(\alpha)}{Cos(\alpha)} }$

Since the denominator of both the values in the denominator is the same:

$\frac{1}{\frac{1-Sin(\alpha)}{Cos(\alpha)} }$

We know that $\frac{1}{\frac{a}{b} }$ = $\frac{b}{a}$ , using the same property:

$\frac{Cos(\alpha)}{1-Sin(\alpha)}$

and we are done!

The radius of the water well is 2r inches. Find the area of the water well.

aleksandrvk [35]

The area of the water well is $4\pi r^2$

<h3>How to determine the area?</h3>

The radius is given as:

Radius, R = 2r

The area of the water well is calculated using:

$A = \pi R^2$

This gives

$A = \pi (2r)^2\\\\\\$

Evaluate the expression

$A = 4\pi r^2$

Hence, the area of the water well is $4\pi r^2$
