Ans. The value of cos (- θ) = cos θ, so it is considered to be an even function. In which quadrant is cos θ is positive and in which quadrant it is negative? Ans. Cos θ is positive in the first and fourth quadrants whereas it is negative in the second and third quadrants....
Cos is one of the 6 trigonometric functions and is widely used in both Mathematics and Physics. The overall concept of trigonometry is based on a right-angled triangle. The value of cos 120° is -1/2 or -0.5 as it lies in the 2nd quadrant where cosine is negative. The formula of ...
quadrant, quarter-circle - a quarter of the circumference of a circle loxodrome, rhumb, rhumb line - a line on a sphere that cuts all meridians at the same angle; the path taken by a ship or plane that maintains a constant compass direction danger line - a line beyond which it is dang...
cartesian plane, the value 180 degree takes place in the second quadrant. as the cosine values in the second quadrant always take a negative value. from the value of cos 0, we will obtain the value of cos 180°. we know that the exact value of cos 0 degrees is 1 so, cos 180 ...
POLARITY ·The AD534 is a 4-quadrant multiplier. This means that , for its two inputs , there are four pos- sible permutations of polarity , and the output product will always be of the correct polarity. The inputs can be mapped on the four quadrants of an X-Y plane , as sho...
Second quadrant: positive sine and negative cosine Third quadrant: sine and negative cosine Fourth quadrant: negative sine and positive cosine Answer and Explanation: Given {eq}\cos \theta = 0.72 \,\, \implies \,\, \text...
quadrants have positive values and the values which lie in the second and third quadrants have negative values. For example, Cos 120°,150°, and 180° have positive values as they lie in the second quadrant while Cos 0° and 30° have negative values as they lie in the first quadrant....
The period is 2π13=6pi. Since there is no vertical shift, the midline is still y=0. Since the period is now 6π, the new points along the x axis coinciding with the quadrantal angles are 6π4=3π2. That is, 3π2 has the same value as 4cos(π2), which is 0, 3π has ...
