Reciprocal in trigonometry math. But cosecant is the reciprocal of the sine of a. Sine cosine of complementary angles. In the six trigonometric ratios sin cos tan csc sec and cot there is a reciprocal relation among them. The secant is the reciprocal of the cosine.

Sine cosine of complementary angles. Cosecant secant and cotangent. Cos θ sec θ. The second one involves finding an angle whose sine is θ.

Underneath the calculator six most popular trig functions will appear three basic ones. The reciprocal sine function is cosecant csc theta 1 sin theta. Our mission is to provide a free world class education to anyone anywhere. But i ll define it.

Sine cosine and tangent and their reciprocals. I will learn how to calculate the related angle from a. So first you have cosecant. Cosecant of a is hypotenuse over opposite.

Khan academy is a 501 c 3 nonprofit organization. Csc a 1 sin a csc a dfrac 1 sin a csc a sin a 1. Csc θ 1 sin θ displaystyle csc theta frac 1 sin theta csc θ. Next are the second reciprocal identity and its counterpart.

So sine of a is opposite over hypotenuse. To find the trigonometric functions of an angle enter the chosen angle in degrees or radians. Trig calculator finding sin cos tan cot sec csc. View 7 2 reciprocal trig ratios and related acute angles pdf from math mcr3u at grimsby secondary school.

The cosecant is the reciprocal of the sine. The reciprocal trigonometric ratios the first one is a reciprocal. The simplest and most basic trig identities equations of equivalence are those involving the reciprocals of the trigonometry functions. Reciprocal relation of trigonometric ratios.

Another way to describe reciprocals is to point out that the product of a number and its reciprocal is 1. Related acute angles learning goal. And cosecant it s always a little bit unintuitive why cosecant is the reciprocal of sine of a even though it starts with a co like cosine. Here the pairs of trigonometric relations are given between which we have reciprocal relation.

Csc left parenthesis a right parenthesis equals start fraction 1 divided by sine left parenthesis a right parenthesis end fraction. To jog your memory a reciprocal of a number is 1 divided by that number for example the reciprocal of 2 is 1 2. Sin θ csc θ. Using reciprocal trig ratios.

Math trigonometry. The reciprocal cosine function is secant.
