Many students think they've solved a trig equation ... the first quadrant, so to find the second solution, we need to use the rule in the second quadrant. From the graph of the function, we ...

Therefore since the trig equation ... angle from the 1st quadrant, so to find the second solution, we need to use the rule in the 2nd quadrant. From the graph of the function, we can see that ...

Figure 3 The arctangent function creates a step change in the curve of the calculated phase lag. Trigonometric tangents are negative in the second and fourth quadrants of a standard phase diagram.

There are four quadrants and ASTC techniques helps you remember if a trigonometric function is positive or negative in each quadrant. ADD - All (Sin, Cos, Tan) are positive SUGAR - Sin is positive ...

First we have proportional parts of all numbers up to 100; then on one page three-place logarithms of numbers and of the six trigonometric functions, natural and logarithmic. On pages 4 and 5 we ...
