Summary
1. Sine of Angle = (Apposite side / Hypotenuse) 2. Cosine of Angle = (Adjacent side / Hypotenuse) 3. Tangent of Angle = (Opposite side / Adjacent side) 4. sine of an angle = cosine of its complement. If sin A = cos B, then A ..
Trigonometry Summary
Summary - sine of an angle = cosine of its complement. If sin A = cos B, then A + B = 90 o . Trigonometric ratios of standard angles (i) sin 0 o = 0, cos 0 o = 1, tan 0 o = 0 (i..

A + C = 90 o C = 90 o - A cos (90 o - A) (2) From (1) and (2), sin A = cos (90 o - A) sine of an angle = cosine of its complement. Similarly we can prove that cos A = sin (90 o - A) Sin A and cos..
