We also know that sin (90°–A) = cos A. Therefore, cos 53° = sin 37°= 3/5 and cos 37° = sin 53° =4/5. Now, we will move on to finding the values of tan 37° and tan 53°. We are aware of the fact that tan (angle) = perpendicular...
Example 2: Using the value of cos 16°, solve: (1-sin²(16°)). Solution: We know, (1-sin²(16°)) = (cos²(16°)) = 0.924 ⇒ (1-sin²(16°)) = 0.924 Example 3: Find the value of 2 cos(16°)/3 sin(74°). Solution: Using trigonometric identities, we know, ...
