To find the value of \ (Ɵ\), calculate sin⁻¹ or cos⁻¹ or tan⁻¹ of the fraction on the right hand side. sin⁻¹ or cos⁻¹ or tan⁻¹ can usually be inputted on a scientific calculator ...

From our ship-mast example before, the relationship between an angle and its tangent can be determined from its graph, shown below. The graphs of sine and cosine are included as well.

Therefore, tan (P) – cot (R) = 0 Q. If sin A = 3/4, calculate cos A and tan A. Sol. Given a triangle ΔABC with right angle at B, Given: Sin A = 3/4 Sin A = Opposite side /Hypotenuse= ¾ ...

A 3,700-year old Babylonian clay tablet reveals an ancient method of constructing right-angled triangles that makes it the world’s oldest and most accurate trigonometric table.

In a right angled triangle the three sides are perpendicular, base and hypotenuse, as shown in the image below. There are three main trigonometric functions - Sine θ (sin θ), Cosine θ (cos θ ...
