Sin θ - Ratio of Perpendicular to Hypotenuse Cos θ - Ratio of Base to Hypotenuse Tan θ - Ratio of Perpendicular to Base Tips and Tricks to Learn Trigonometric Formulas, Table and Signs Easily ...

tan θ = sin θ cos θ As the point P moves anticlockwise round the circle, the values of cos θ and sin θ change, therefore the value of tan θ will change. The graph has a period of 180°.

Students are also taught many formulas in CBSE Class 12, especially in calculus chapters like Inverse Trigonometric Functions. Formulas, theorems and other maths rules help simplify equations and ...
