Trigonometry Formulas Sheet For Class 10

Class 10 chapter- Introduction to Trigonometry Formula Definition of Angle If we rotate a line segment with respect to any of its endpoints, then the amount of rotation is called an angle. If rotation exists in an anti-clockwise direction, the angle is said to be positive, otherwise negative.

Trigonometric Ratios For Any Right-Angled Triangle sineθ =sinθ, cosineθ = cosθ, tangentθ = tanθ, cosecantθ = cosecθ, secantθ = secθ

Where p→perpendicular, h→ hypotenuse, b→ base
