Given tan theta= -9/4, where 270 degrees is less or equal than theta and less or equal than 360 degrees
tan(t) = -9/4, 270 <= t <=360
-----------------------
tan = y/x = -9/4
In Q4, y = -9, x = 4
----
r = sqrt(x^2 + y^2) = sqrt(97)
---------------------
a) state the other five trigonometric ratios as fractions.
sin = y/r
cos = x/r
--
cot = 1/tan
sec = 1/cos
csc = 1/sin
================
b) determine the value of theta to the nearest degree.
Use a calculator.
