Hint: To solve this problem, we will write tan A in terms of sin A and cos A (that is tan A = sin A cos A ). We will then square both the sides. We can then express cos 2 A = 1 − sin 2 A to get tan 2 A in terms of sin 2 A. We can then get the value of tan A by performing the square root on both sides of the equation. sok sreyneang pictureWebb30 mars 2024 · In Trigonometry Formulas, we will learn.
