Cos -270

3. Cos(270 - X) is in 3rd quadrant (Tan,Cot only positive) and angle is 270 so we have to change Cos as Sin. therefore. Cos(270 - X) = -Sin X. 4. Cos(270 + X) is in 4th quadrant ( Cos is positive) and angle is 270 so we have to change Cos as Sin. therefore. Cos(270 + X) = Sin X

Cos(270 - X) = -Sin X. 4. Cos(270 + X) is in 4th quadrant ( Cos is positive) and angle is 270 so we have to change Cos as Sin. therefore. Cos(270 + X) = Sin X Trigonometric ratios of 270 degree minus theta is one of the branches of ASTC formula in trigonometry. Trigonometric-ratios of 270 degree minus theta are given below.

Consider the unit circle (a circle with radius 1). On the unit circle as graphed on an xy coordinate plane, with 0 degrees starting at (x,y) = (1,0): graph{x^2+y^2=1 [-1, 1, -1, 1]} If we draw a line from the origin at the angle we seek, then where that line intersects the unit circle, the sin of the angle will be equal to the y Cos 0 =1 Cos 90 = 0 Cos 180 = -1 Cos 270 = 0 Cos 360 = 1 Find the Exact Value cos(270 degrees ) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant .

Dec 16, 2014 · On the unit circle, the coordinates of a 270° angle are (0, -1). At this point x-value = 0, y-value = -1, r-value (the distance from the origin to the point) = 1. sin = y/r cos = x/r tan = y/x csc = r/y sec = r/x cot = x/y. sin(270°) = -1/1 = -1 csc(270°) = 1/-1 = -1 Use this simple sine calculator to calculate the sine value for 270° in radians / degrees. The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and calculate the exact sine 270° value easily.

In trigonometrical ratios of angles (90° + θ) we will find the relation between all six trigonometrical ratios. When I use the cos function on a calculator cos(0) = 1, cos(90) = 0 cos(180) = -1 and cos(270) = 0. However I don't know how to produce these results in my code. The result I receive in my code are Trigonometric ratios of 270 degrees plus theta (270 + θ) We will prove the trigonometric ratios of 270 degrees plus theta (270 + $\Theta$) using the trigonometric ratios of (180 + $\Theta$).

Tangens en cotangens zijn goniometrische functies.De naam tangens komt van raaklijn in het Latijn (tangens betekent rakend). Het argument van de tangens en de cotangens wordt vaak gezien als een hoek en dat heeft te maken met de oorspronkelijke definitie van deze functies. De tangens was gedefinieerd als de verhouding van de overstaande en de aanliggende rechthoekszijde in een …
