WebFor cos 1 degrees, the angle 1° lies between 0° and 90° (First Quadrant ). Since cosine function is positive in the first quadrant, thus cos 1° value = 0.9998476. . . Since the cosine function is a periodic function, we can represent cos 1° as, cos 1 degrees = cos (1° + n × 360°), n ∈ Z. ⇒ cos 1° = cos 361° = cos 721°, and so on. WebApr 10, 2024 · We can find the sign of cos(-885) using the fact that cosine is an even function, which means that: cos(-x) = cos(x) for any value of x. Therefore, we have: cos(-885) = cos(885) To determine the sign of cos(885), we need to know the quadrant in which the angle 885 degrees lies. Starting from the positive x-axis and rotating …
WebSine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle:. For a given angle θ each ratio stays … Webcos (135) cos ( 135) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. −cos(45) - cos ( 45) The exact value of cos(45) cos ( 45) is √2 2 2 2. − √2 2 - 2 2. The result can be shown in multiple forms.
WebMar 16, 2024 · For cos For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90° Cos is the opposite of sin. We should learn it like cos 0° = sin 90° = 1 cos 30° = sin 60° = √3/2 cos 45° = sin 45° = 1/√2 cos 60° = sin 30° = 1/2 cos 90° = sin 0° = 0 So, for cos, it will be like 1, √3/2, 1/√2, 1/2, 0
