Trigonometry Formulas For Class 10
Trigonometry is an important part of math. Trigonometry is important in terms of board examination. Therefore, to solve the problems of trigonometry, it is necessary to remember the formulas. For this reason, in this article of All Trigonometry Formulas For Class 10, 11, 12, we have shown how to remember through logic.
Sine, Cosine, and Tangent
Trigonometric Ratio
In a right-angled triangle, the opposite side of a given angle is perpendicular, the opposite side of the right angle is the hypotenuse and the third side is the base.
In ΔABC,
∠=90°,∠C=θ
∴ The side AC is the hypotenuse,
AB is perpendicular
and BC is the base.
From the Pythagoras theorem,
Hypotenuse2 = oppsite2 ∔ adjacent2

Relationship between arms and angles
Finding the formulas of cosec, sec, and a cot can be obtained by reversing the formulas of sin, cos, and tan.
This means that the formula of cosec will be the inverse of sin, the formula of sec will be the inverse of sec, the formula of cot will be inverse of tan. The numerator is replaced by the numerator and denominator.
