The t-ratios of acute angles are given in tables of natural sines, natural cosines and natural tangents. In this chapter, we will discuss (i) how to read trigonometric tables, (ii) how to find the angle when the value of a t-ratio is giv..

We define (e x +e - x )/2 as sinhx and (e x -e -x )/2 as coshx. Based on this other trigonometric functions are defined and they are all called hyperbolic function..

Trigonometric tables are used - to find the value of a t-ratio when the angle is given - to find the angle when the value of the t-ratio is given As an angle increases, the sine ratio increases, the cosine ratio decreases and the tangent ratio increases..

i. The trigonometric ratio's are: Sine, Cosine, Tangent, Cotangent, Secant, and Cosecant. ii. sin A = cos (90 o - A). iii. sin A / cos a = tan A...

The circular functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equiva..

Differentiation of certain functions seem to be very difficult, but by suitably substituting the independent variable with some trigonometric function or other functions, they can be differentiated easily.Differentiation of certain functions seem to be very difficult, but by suitably subs..

The angles (2 p + A), (4 p + A)......have the same initial and terminal arm as the angle A and so these angles are called co-terminal angles . For all such angles, the value of any trigonometric ratio is the same. Thus, all co-terminal angles are trigonometrically equivalent. Le..

(i) Sin q means a particular ratio. It is not sin multiplied by q . (ii) For trigonometrical ratios, short form T-ratios will be used. (iii) In right angled triangles T-ratios are obtained only for acute angles. (iv) T-ratios depend on only the magnitude of the ..
