Question 1160460
A) If sinA=-1/25 and angle A terminates in quadrant IV, what does tanA equal?

B) Given tan theta=7/24, and theta terminates in Quadrant III, determine the value of cos theta.

C) If sin theta= 1/2 and theta terminates in Quadrant II, what is the valuse of csc theta * cot theta? 
<pre>I'll only do A) for you, and none of these are done the way the other 2 RESPONDENTS state. 
While NOT requested, answers of these forms are generally EXACT!
With &#8737A being in Q IV, we get: {{{matrix(2,7, sin (A), "=", (- 1)/25, "=", O/H, "=", (- y)/r, x, "=", sqrt(25^2 -  (- 1^2)), "=", sqrt(624), "=", 4sqrt(39))}}}
                               {{{highlight_green(matrix(1,9, tan (A), "=", O/A, "=", (- y)/x, "=", (- 1)/(4sqrt(39)), "=", (- sqrt(39))/156))}}}
That's how SIMPLE A) is!!
