Step 1

Simplify each term.

Step 1.1

Rewrite the division as a fraction.

$\cos (A) + \sin (A) = \tan (A) + \frac{1}{\sec (A)}$

Step 1.2

Rewrite $\sec (A)$ in terms of sines and cosines.

$\cos (A) + \sin (A) = \tan (A) + \frac{1}{\frac{1}{\cos (A)}}$

Step 1.3

Multiply by the reciprocal of the fraction to divide by $\frac{1}{\cos (A)}$ .

$\cos (A) + \sin (A) = \tan (A) + 1 \cos (A)$

Step 1.4

Multiply $\cos (A)$ by $1$ .

$\cos (A) + \sin (A) = \tan (A) + \cos (A)$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$A \approx 0, - 3.14159265, 3.14159265, - 6.284375, 6.284375, - 9.42477796, 9.42477796$
