Metabolism is the total amount of the biochemical reactions involved in maintaining the living condition of the cells in an organism. All living organisms require energy for different essential processes and for producing new organic substances. The metabolic processes help in growth…
Q1 What do you Mean by Trigonometry? Trigonometry is one of the branches of mathematics which deals with the relationship between the sides of a triangle (right triangle) with its angles. There are 6 trigonometric functions for which the relation…
Example 1: Two friends, Rakesh and Vishal started climbing a pyramid-shaped hill. Rakesh climbs 315 m and finds that the angle of depression is 72.3 degrees from his starting point. How high is he from the ground? Solution: Let m…
There are many real-life examples where trigonometry is used broadly. If we have been given with height of the building and the angle formed when an object is seen from the top of the building, then the distance between object…
The three basic functions in trigonometry are sine, cosine and tangent. Based on these three functions the other three functions that are cotangent, secant and cosecant are derived. All the trigonometrical concepts are based on these functions. Hence, to understand…
The Trigonometric formulas or Identities are the equations which are true in the case of Right-Angled Triangles. Some of the special trigonometric identities are given below – For angles u and v, we have the following relationships: Sine Laws Cosine Laws Trigonometry…
The concept of unit circle helps us to measure the angles of cos, sin and tan directly since the centre of the circle is located at the origin and radius is 1. Consider theta be an angle then, Suppose the…
Check the table for common angles which are used to solve many trigonometric problems involving trigonometric ratios. Angles 0° 30° 45° 60° 90° Sin θ 0 ½ 1/√2 √3/2 1 Cos θ 1 √3/2 1/√2 ½ 0 Tan θ 0 1/√3 1…
The trigonometry angles which are commonly used in trigonometry problems are 0°, 30°, 45°, 60° and 90°. The trigonometric ratios such as sine, cosine and tangent of these angles are easy to memorize. We will also show the table where all the…
The trigonometric function can be described as being even or odd. Odd trigonometric functions: A trigonometric function is said to be an odd function if f(-x) = -f(x) and symmetric with respect to the origin. Even trigonometric functions: A trigonometric function is…
