Cosine of 220
WebFeb 13, 2024 · The general equation for a sinusoidal function is: f (x)=±a⋅sin (b (x+c))+d The ± controls the reflection across the x -axis. The coefficient a controls the amplitude. The constant d controls the vertical shift. Here you will see that the coefficient b controls the horizontal stretch.

WebSep 28, 2024 · cot 150° = cot (2 × 90° – 30°) = -cot 30° = -√3. Explanation Here, even a coefficient of 90° is present, so cot remains as it is and it’s coming to be in the second quadrant where only sin and cosec are positive and the rest all are negative. Hence, we get -cot 30°.
