WebAs we know, sin 45° = 1/√2 Also, by trigonometric identities, we know that, Sin 2 x + cos 2 x = 1 Or Cos 2 x = 1 – sin 2 x Put x = 45° Cos 2 45° = 1 – sin 2 45° Put the value of sin 45° in … WebJun 30, 2024 · Sin 45° = 12 Sin 60° = 32 Sin 90° = 1 The values of Sin θ at different angles respectively is mentioned below: Since, sin and cos are opposite to each other so their values would be opposite to each other. To explain this we will list down the values of cos. VALUES OF COS θ AT DIFFERENT ANGLES: The value of cos θ are as following: chubb insurance company of canada careers
The Exact Values for Sine, Cosine, and Tangent of 45 Degrees
WebThe sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. In the illustration below, sin (α) = a/c and sin (β) = b/c. From cos (α) = a/c follows that the sine of any angle is always less than or equal to one. WebMar 29, 2014 · 7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ...
