in the cartesian plane takes place in the second quadrant. therefore, the value of sin pi in the second quadrant is always positive. from the value of sin 0, we will obtain the value of sin 180. we know that the exact value of sin 0 degree is 0. so, sin 180 degree is +(sin 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). Therefore, the value of cos 180 degrees = −1....
What is the Value of Sec 0 Degrees? The value of sec 0 degrees is 1. Sec 0 degrees can also be expressed using the equivalent of the givenangle(0 degrees) in radians (0 . . .) We know, usingdegree to radianconversion, θ in radians = θ in degrees × (pi/180°) ⇒ 0 degre...
