What is the function of an angle?

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

What is the value of the missing angle?

Help: Since the two angles are supplementary, their sum is 180°. To find the missing angle, subtract the given angle from 180°. The result is the missing angle.

What is the measure of a angle?

The measure of an angle is determined by the amount of rotation from the initial side to the terminal side. One way to measure an angle is in terms of degrees . A measure of one degree ( 1° ) is equivalent to a rotation of 1360 of a complete revolution.

What is the general angle?

If angle θ is a quadrantal angle, then either x or y will be 0, yielding the undefined values if the denominator is zero. The sign, positive or negative, of the trigonometric functions depends on which quadrant this point A (x, y) is located in.

What is the value of angle Z?

Answer: Also, angles y and z lie in a straight line, therefore they are supplementary angles and their sum is equal to 180∘. So, the value of angle z is, z=180∘−58∘=122∘.

How to find values of trigonometric functions of any angle?

The following steps will be useful to find the value of trigonometric functions for any angle. Step 1 : To find the value of any trigonometric angles, first we have to write the given angles in any one of the following forms. Trigonometric ratios of angles greater than or equal to 360 degree. Trigonometric ratios of complementary angles.

How to find the value of an angle?

To find the value of any trigonometric angles, first we have to write the given angles in any one of the following forms. If the given angle measures more than 360 degree, we have to divide it by 360 and write the remainder in one of the above forms.

Are there two types of functions of angles?

Technically, we have two different types of cosines and sines: one defined as functions of arcs and the other as functions of angles. However, the connection is so close and the distinction so minor that we will often interchange the terms circular and trigonometric.

Can a function of any angle equal plus or minus?

A function of any angle will equal plus or minus that same function of the corresponding acute angle. The sign will depend on the quadrant. First, if θ is a second quadrant angle, then r will terminate at a point
