Let s see the angles in different Quadrants In Quadrant 1, angles are from 0 to 90 In Quadrant 2, angles are from 90 to 180 In Quadrant 3, angles are from 180 to 270 In Quadrant 4, angles are from 270 to 360 To
In the first quadrant, the values for sin, cos and tanare positive. In the second quadrant, the values for sin are positive only. What quadrants is sin negative? The sine ratio is y/r, and the hypotenuse r is always positive. So the sine will be negative when y is negative, which ...
735° = 15° ---> tan 735° =tan 15° 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. S...
Evaluate the integral_{0}^{fraction {pi}{2} }7^{cos t} sin t . dt Let y = 20 sin (2 x), as x increases from pi / 3 to pi / 3 + 1, calculate d y and Delta (y). Why is tangent positive in quadrants 1 and 3? Find the exact value of the expression. sin (-6 pi)...
tan(θ)=2tan(θ)=2 , sin(θ)<0sin(θ)<0 The sine function is negative in the third and fourth quadrants. The tangent function is positive in the first and third quadrants. The set of solutions for θθ are limited to the third quadrant since that is the only quadrant found in ...
Given tan theta = 7 / 24, and theta terminates in quadrant III. What is the value of cos theta? Indicate the quadrants in which the terminal side of \theta must lie under the following conditions. (Select all that apply.) \sin \theta is posi...
In the fourth quadrant, you’ll have a positive x value and a negative y value. All these are parts of the entire unit circle. The unit circle chart also involves sin, cos, tan, sec, csc, cot. Fortunately, you don’t have to memorize everything involved in the entire unit circle. ...

Positive Values of Sine Function:In any right-angled triangle, the ratio of the opposite side to the hypotenuse side is known as the sine function. For any angle (θ), it is written as sinθ. Its value is positive in the first and second quadrants....
In which quadrants do sine and cosine functions have the same sign? Find the exact value of the real number y. (a) y = arcsin (3/ 2) (b) y = arccos (3/2) The value of \sin x is given. Find \cos x and \tan x, if x lies in the specified in...
