Tan θ = Opposite side / Adjacent side = CB / AB Sin θ = Opposite side / Hypotenuse = BC / CAĬos θ = Adjacent side / Hypotenuse = AB / CA Now as per sin, cos and tan formulas, we have: The three sides in the right-angled triangle are given below: Suppose ABC is a right-angled triangle, right-angled at B, as shown in the figure below: The three ratios sin, cos, and tan have their individual formulas. ‘Sin cos tan table’ consists of sin, cos and tan values of standard angles 0°, 30°, 45°, 60° and 90°, sometimes other angles like 180°, 270°, and 360° also. The trigonometric functions sin, cos and tan are the primary functions we consider while solving trigonometric questions.
