Trigonometric Functions

Do you know how to measure an angle in radians? And how the properties of the sides and angles of a triangle define the branch of maths knows as Trigonometry? Trigonometry formula build the basics of mathematics across all the major branches. Let’s learn about the trigonometic functions, angles and equations in the topics below.

FAQ on Trigonometric Functions

Ques. When was trigonometry invented?

Ans. In the middle of the first century BC, Hipparchus was the first-ever person to treat the trigonometry as a practical and applicable science. Moreover, he was also the first person to pile up a table of the chords. Menelaus impressively advanced the ground of the spherical trigonometry.

Ques. Are algebra and trigonometry the same?

Ans. Algebra and trigonometry are both mathematics subjects. Most of the high school students require to study this before going into graduation. These 2 subjects are also taught in colleges. These 2 math subjects are very important to learn and strong knowledge in both these subjects is required before entering into any calculus course.

Ques. What are the trigonometric ratios?

Ans. There are a total of 6 trigonometric ratios and these are; sine, cosine, tangent, cosecant, secant, and cotangent. These 6 trigonometric ratios are shortened by name as sin, cos, tan, cosec, sec, cot. These are said to be the ratios since they are expressible in the terms of the sides of a triangle that has a right angle in it for a specific angle i.e. θ.

Ques. Which jobs use trigonometry?

Ans. The trigonometry is useful for engineers, medical technicians, mathematicians, data entry professionals, statisticians, drafters, chemists, boilermakers, millwrights, etc.
