We can represent the tangent function in terms of the secant function using trig identities, tan 30° can be written as √(sec²(30°) - 1). Here, the value of sec 30° is equal to 1.1547. What is the Value of Tan 30 Degrees in Terms of Sin 30°?
so the value of the cosine at this particular angle is the division of 0.8660254037 The value of sec 30 will be the exact reciprocal of the value of cos 30.
Examples Using Sec 70 Degrees Example 1: Using the value of sec 70°, solve: (1 + tan²(70°)). Solution: We know, (1 + tan²(70°)) = (sec²(70°)) = 8.5486 ⇒ (1 + tan²(70°)) = 8.5486 Example 2: Find the value of sec 70° if cos 70° is 0.3420. ...
Sine, cosine and tangent are the three main pillars on which the whole concept of trigonometry rests. Sin is one of those important trigonometric ratios. The value of sin 30 degrees is half (½). Just to recapitulate the sides of a triangle, let's go through the following definitions on...
