Is csc positive in quadrant 2
WebQuadrant 1 of theta. sin, csc, cos, sec, tan, and cot positive. Quadrant 2 of theta. sin & csc positive. cos & sec negative. tan & cot negative. Quadrant 3 of theta. sin & csc negative. … WebThe distance from a point to the origin is always positive, but the signs of the x and y coordinates may be positive or negative. Thus, in the first quadrant, where x and y coordinates are all positive, all six trigonometric functions have positive values. In the second quadrant, only sine and cosecant (the reciprocal of sine) are positive.

WebJul 7, 2024 · In Quadrant I, both the x– and y-coordinates are positive; in Quadrant II, the x-coordinate is negative, but the y-coordinate is positive; in Quadrant III both are negative; and in Quadrant IV, x is positive but y is negative. Why is cos negative in 2nd quadrant? Since r is always positive, then ry will always be positive in quadrant II. … WebThis is because up until 90 degrees (or pi/2 radians) the circle is in quadrant 1 at the right angle when it reaches the y axis y is still positive, but now x is 0 quadrant 2 has x negative now, since it is on the left of the y axis. if it's easier you can remember x = 1 is on the right of the y axis, and x = -1 is on the left.
