Since we know that cosecant is the reciprocal of sine, secant is the reciprocal of sine, and cotangent is the reciprocal of tangent, we can construct these functions as follows: sec A = 1 cos A = 25 24 csc A = 1 sin A = 25 7 cot A = 1 tan A = 24 7.
The secant function is the reciprocal of the cosine function. In Figure 5.4.1, the secant of angle t is equal to 1 cost = 1 x, x ≠ 0. The secant function is abbreviated as sec. The cotangent function is the reciprocal of the tangent function. In Figure 5.4.1, the cotangent of angle t is equal to cost sint = x y, y ≠ 0.
‘Sin cos tan table’ consists of sin, cos, and tan values of standard angles 0°, 30°, 45°, 60°, and 90°, and sometimes other angles like 180°, 270°, and 360° also. Provided below is a chart that can be used to determine the angles. The sin cos and tan table helps to find the values of trigonometric standard angles such as 0°, 30

To calculate using sin, cos and tan, we need to know their trigonometric ratios (remember that the ratio of two values is a division of these values). Consider the right-angled triangle below. Consider the right-angled triangle below.

Finding Sin Cos Tan Values [Click Here for Previous Year Questions] Here, to find the sin, cos, tan values, Divide 0,1,2,3, and 4 by 4, then consider their positive roots of them. It can help get the sine ratios, which are, 0, ½, 1/√2, √3/2, and 1 for the angles 0°, 30°, 45°, 60° and 90°.
Letting the positive x -axis be the initial side of an angle, you can use the coordinates of the point where the terminal side intersects with the circle to determine the trig functions. The figure shows a circle with a radius of r that has an angle drawn in standard position. The equation of a circle is x2 + y2 = r2.
From the sin graph we can see that sinø = 0 when ø = 0 degrees, 180 degrees and 360 degrees. Note that the graph of tan has asymptotes (lines which the graph gets close to, but never crosses). These are the red lines (they aren't actually part of the graph). Also notice that the graphs of sin, cos and tan are periodic. Evaluate inverse trig functions. The following are all angle measures, in degrees, whose sine is 1 . Which is the principal value of sin − 1 ( 1) ?
269. You can use a function like this to do the conversion: function toDegrees (angle) { return angle * (180 / Math.PI); } Note that functions like sin, cos, and so on do not return angles, they take angles as input. It seems to me that it would be more useful to you to have a function that converts a degree input to radians, like this:
