For the whole circle we need values in every quadrant, with the correct plus or minus sign as per Cartesian Coordinates:Note that cos is first and sin is second, so it goes (cos, sin):Save as PDFExample: What is cos(330°) ? Make a sketch like this, and we can see it is the ...
Fig. 2. Unit circle with quadrants added. The first quadrant is top right, second quadrant is top left, third quadrant is bottom left and fourth quadrant is bottom right. © HowStuffWorks 2021 We can use (x, y) coordinates to describe any point along the outer edge of the circle. ...
For which of the quadrant angles 0, pi/2, pi , and 3pi/2 is the sine function equal to 0? Which trig function is sec - 1 / 1 - cos ? Use the unit circle to find all values of theta between 0 and 2 for which the given statement is true. c o s = 2 2 = ___ rad The...
The unit circle represents a complete angle of 2π radians. And the unit circle is divided into four quadrants at angles of π/2, π. 3π/2, and 2π respectively. Further within the first quadrant at the angles of 0, π/6, π/4, π/3, π/2 are the standard values, which are...
