If the angle is multiple of π/2, ie π/2, 3π/2, 5π/2, then sin becomes cos cos becomes sin If the angle is multiple of π, ie π, 2π, 3π, then sin remains sin cos remains sin 2The sign depends on the quadrant angle is in sin (π/2 – x) Since it is π/2, sin will become cos Here x is an acute angle So, π/2 – x = 90 – x is anTrigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved Some like the following sin 2 ( x ) cos 2 ( x ) = 1 1 tan 2 ( π 2 − x ) = sec ( x )Sin 90° = 1 The most common trigonometric sine functions are Sin 90 degree plus theta Sin 90 degree minus theta Some other trigonometric sine identities are as follows Sin 2x = 2 sin x cos x In the same way, we can derive other values of sin angles like 0°,

I hope you know that π/2 rads = 90 degrees This is the graph of y = sin(x) from x = 360 to 7 degrees Now if we consider sin(n × 90) w We say the cosine curve is a sine curve which is shifted to the left by `π/2\ (= 157 = 90^@)` The value of the cosine function is positive in the first and fourth quadrants (remember, for this diagram we are measuring the angle from the vertical axis),The value of sin (π 2) is fairly well known to be 1 sin − 1 (1) Since the inverse sin function doesn't know where that 1 came from, it has to assume it came from angles between − π 2 and π 2 That means it will evaluate that inverse sine to π 2 This same reasoning can be used for a value of 10 sin (10) ≈ − 0

Welcome to sin π/2, our post aboutthe sine of π/2 radians For the sin of minus π/2 radians we use the abbreviation sin for the trigonometric function and write it as sin π/2 If you have been looking for what is sin π/2, or if you have been wondering about sin π/2 radians in degrees, then you are right here, too In this post you can find the sin π/2 value, along with identitiesNotation Several notations for the inverse trigonometric functions exist The most common convention is to name inverse trigonometric functions using an arc prefix arcsin(x), arccos(x), arctan(x), etc (This convention is used throughout this article) This notation arises from the following geometric relationships citation needed when measuring in radians, an angle of θSin (nπ/2) can not be given a general value When n is even, nπ/2 becomes an integral multiple of π Thus, sin (nπ/2) will be zero If n is of the form 4k1,
