text: Also, notice that the values of the trigonometric functions can be either positive or negative because x-coordinates and y-coordinates can also be either positive or negative.
text: Also, notice that the values of the trigonometric functions can be either positive or negative because x-coordinates and y-coordinates can also be either positive or negative.
text: Because the triangle is in the third quadrant, both the x and y values should be negative.
text: (Sometimes the value of B inside the function will be negative, which is why there are absolute-value bars on the denominator.)
text: Since x lies in the third quadrant, the value of \( \sec{x} \) will be negative.
text: If x is negative, the value of the inverse will fall in the quadrant in which the direct function is negative.
text: Notice how the sine values are positive between 0 and which correspond to the values of the sine function in quadrants I and II on the unit circle, and the sine values are negative between and which correspond to the values of the sine function in quadrants III and IV on the unit circle.
text: The equation shows a minus sign before Therefore can be rewritten as If the value of is negative, the shift is to the left.
text: Thus, in the first quadrant, where x and y coordinates are all positive, all six trigonometric functions have positive values.
text: If x is positive, then the value of the inverse function is always a first quadrant angle, or 0.
text: Therefore, the sine value is positive, so sin θ = 15 4 {\displaystyle {
