Here is a simple interactive app to illustrate the changes in signs of the three basic trigonometry ratios – Sine, Cosine Tangent in the four quadrants. Rotate the angle by mouse or touch to …

In the first quadrant, all functions are positive, in the 2nd quadrant, only sin and cosec are positive, in the 3rd quadrant only tan and cot are positive, whereas in the 4th quadrant only …

Cosine, written as cos⁡ (θ), is one of the six fundamental trigonometric functions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles …

2024年1月2日 · Signs (Plus/Minus) of Cotangent, Secant, and Cosecant in All Quadrants The reciprocal of a number retains the sign of the original number. Therefore, in all the quadrants: …

To understand how the values of trigonometric ratios change in different quadrants, first we have to understand ASTC rule. ASTC Rule : ASTC rule is nothing but "all sin tan cos" rule in …
