Sin θ 3 2 0.
Find value of trig function math. Cosecant secant and cotangent. θ lies in the third or fourth quadrant. Determine the exact value of each of the following without using a calculator. Since 360 represents one full revolution the trigonometric function values repeat every 360.
How to use the unit circle to find exact values of trigonometric functions. But principal value must be in π 2 π 2 in the first quadrant we get only we get positive values for all trigonometric ratios so we have to choose one of the angles from 0 to π 2 that is negative angle. Sine cosine and tangent and their reciprocals. Finding trigonometric values given one trigonometric value other info example 2.
In this video we are given the value of one trig function along with the quadrant where the angle belongs and use it to find the value of the other trig functions. Try the given examples or type in your own problem and check your answer with the step by step explanations. A 1 so our amplitude is equal to 1. Another way to find this same value is to set the inside of the parenthesis equal to 0 then solve.
Underneath the calculator six most popular trig functions will appear three basic ones. Evaluate tan 121π 4 evaluate sec 29π 6 try the free mathway calculator and problem solver below to practice various math topics. To find the value of any trigonometric angles first we have to write the given angles in any one of the following forms. To find amplitude look at the coefficient in front of the sine function.
For example sin360 sin0 cos 390 cos 30 tan540 tan 180 sin 45 sin315 etc. The following steps will be useful to find the value of trigonometric functions for any angle. Therefore the period of this function is equal to 2. 3tan3 a tan a 0 a 0 360 2 cos 2 left x right sqrt 3 cos left x right 0 0 circ 2cos2 x 3 cos x 0 0 x 360.
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. To find the phase shift take c b or. Cosec θ 2 3. How to find values of trigonometric functions of any angle.
