WebExplanation: For cos 2pi/3, the angle 2pi/3 lies between pi/2 and pi (Second Quadrant ). Since cosine function is negative in the second quadrant, thus cos 2pi/3 value = - (1/2) or -0.5. Since the cosine function is a periodic function, we can represent cos 2pi/3 as, cos 2pi/3 = cos (2pi/3 + n × 2pi), n ∈ Z. ⇒ cos 2pi/3 = cos 8pi/3 = cos ...

WebTherefore, SIN/COS = TAN/1 . You can also see that 1/COS = SEC/1 and 1^2 + TAN^2 = SEC^2. A bunch of those almost impossible to remember identities become easier to remember when the TAN and SEC become legs of a triangle and not just some ratio of other functions. The angle line, COT line, and CSC line also forms a similar triangle. WebIn this article, we will discuss the methods to find the value of sin pi/2 with examples. Sin pi/2: 1; Sin (-pi/2):-1; Sin pi/2 in degrees: sin (90°) What is the Value of Sin pi/2? The value of sin pi/2 is 1. Sin pi/2 can also be expressed using the equivalent of the given angle (pi/2) in degrees (90°).
Webrewrite in terms of sine and cosine and and write the expression as a numerical value, or in terms of a single trigonometric function if possible. to find the inverse of a reciprocal trigonometric function: 1. rewrite in terms of sine and cosine, using the reciprocal of the given value. 2. find the angle measure. Simplify: sec (θ) sin (θ) cot ... WebJun 9, 2024 · sin(pi/4) = sqrt2/2 cos(pi/4) = sqrt2/2 tan(pi/4) = 1 csc(pi/4) = sqrt2 sec(pi/4) = sqrt2 cot(pi/4) = 1 pi/4 radians is the same as 90 degrees. So, first draw a right triangle with an angle of pi/4: This creates a 45-45-90 triangle, also known as a right isosceles triangle. This is a very special triangle, and we know that both of its legs will be the same length, …
