<PRE><B>Question 1128094</B>

Trigonometry-basics/1128094 (2018-11-05 16:42:40): A point P is on the terminal side of angle theta. Evaluate the six trigonometric functions for theta.
P(4, -7)
---------------
Note: P is in QIV where sin and tan are negative
x = 4 ; y = -7 ; r = sqrt(4^2+7^2) = sqrt(65)
-------- 
Sin(theta) = y/r = -7/sqrt(65)
cos(theta) = x/r = 4/sqrt(65)
Tan(theta) = y/x = -7/4
Csc(theta) = r/y = -sqrt(65)/7
Sec(theta) = r/x = sqrt(65)/4
cot(theta) = x/y = -4/7
