Is trig easy?
Trigonometry is the study of triangles. It is very easy if approached in a right way. Trigonometry is all about the relation between the sides and angles of the triangles. In this article, we will discus how to learn trigonometry basics in 5 steps.
Who is called Father of trigonometry?
The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. Although these tables have not survived, it is claimed that twelve books of tables of chords were written by Hipparchus. This makes Hipparchus the founder of trigonometry.
What is cos over sin?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
What are all the formulas of trigonometry?
Trigonometric Formulas: Trigonometric identities and formulae are based on right-angled triangle. They are: Pythagorean Formula: For the above right-angled triangle, the sum of the squares of base and height is equal to the square of the hypotenuse.
What are all the trigonometric formulas?

How do you calculate trigonometry?
Trig calculator finding sin, cos, tan, cot, sec, csc. To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Underneath the calculator, six most popular trig functions will appear – three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent.
How many formulas are there in trigonometry?
Trigonometry Functions Formulas There are basically 6 Laws used for finding the elements in Trigonometry. They are called trigonometric functions. The six trigonometric functions are sine, cosine, secant, co-secant, tangent and co-tangent. Moreover, what are the 3 trig functions?
