True or False $s e c 胃 = \frac{1}{\sin 胃}$ .

Short Answer

Expert verified

The formula $s e c 胃 = \frac{1}{\sin 胃}$ is false.

Step by step solution

01

Step 1. Given information.

We have:

$s e c 胃 = \frac{1}{\sin 胃}$

02

Step 2. Find whether the formula is true or false.

The formula is $s e c 胃 = \frac{1}{s i n 胃}$ .

The reciprocal identity of secant is:

$s e c 胃 = \frac{1}{\cos 胃}$

Hence, the given formula $s e c 胃 = \frac{1}{s i n 胃}$ is false.
