Hence, tan 735° is equal to tan 15°. Problem 2 : Evaluate : cos (-870°) Solution : Since the given angle (-870°) has negative sign, we have to assume it falls in the fourth quadrant. In the fourth quadrant, "cos" is positive. So, we have cos (-870°) = cos 870°. Th...
Thus, cos ɸ is the ratio of the leg adjacent to ɸ and the hypotenuse, and sin ɸ is the ratio of the leg opposite ɸ and the hypotenuse. The arc AB of the circle is called the first quadrant of the circle, and the arcs BA’, A’B’, and B’A are called the second,...
Find sin2x,cos2x, and tan2x if tanx=34 and x terminates in quadrant III. Trigonometric Identities: Trigonometric identities refer to equations involving trigonometric functions which are true for any angle value. The following are some examples: Cosine Double-A...
will come in iind quadrant for any angle subtracted from 180°, sin will not be changed to cos the sign of sine ratio in the second quadrant will remain positive how to derive the value of sin 180 degrees? the value of sin 180 (sin pi) can be interpreted in terms of different ...

Cos 180 degrees = −1. Tan 180 degrees = 0. Sec 180 degrees = −1. Cot 180 degrees = Undefined 3. What is the value of Cos 180 degrees? We know that the exact value of cos 0 degrees is 1. So, cos 180 degrees which can be written as −(cos 0) is equal to −(1)....
This takes the sin and cos algorithms from Optimized Routines under MIT license, and converts them to Numpy intrinsics. The routines are within the ULP boundaries of other vectorised math routines (<4ULP). The routines reduce performance in some special
