Question 1024602: Someone PLEASE help !!!!!!
Evaluate the expression under the given conditions.
sin(θ − ϕ); tan θ = 3/4, θ in Quadrant III, sin ϕ = −3 sqrt 10/10 , ϕ in Quadrant IV
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Evaluate the expression under the given conditions.
sin(t − p);
tan(t) = 3/4, t in Quadrant III,
sin(t) = -3/5
cos(t) = -4/5
---------------------------
sin (p) = −3 sqrt 10/10 , ϕ in Quadrant IV
cos(p) = sqrt[10^2-9*10]/10 = sqrt(10)/10
-----
sin(t-p) = sin(t)cos(p)-cos(t)sin(p)
------
Ans: Substitute the sin and cos values to get the answer
