<PRE><B>Question 824066</B>
3sin(x) + sin(x)*cos(x) = 2cos(x)
----
3sin(x) + sin(x)cos(x) -2cos(x) = 0
---
3sin(x) + 3sin(x)cos(x)-2sin(x)cos(x) - 2cos(x) = 0
-----------
Rearrange:
3sin(x)-2sin(x)cos(x) + 3sin(x)cos(x)-2cos(x) = 0
----
Factor:
sin(x)[3-2cos(x)] + cos(x(3-2cos(x) = 0
----
(3-2cos(x)(sin(x)+cos(x) = 0
----
cos(x) = 3/2 (that is extraneous)
----
sin(x) = -cos(x) 
x = 135 degrees or (3/4)pi radians
======================================

4sin(x)-sin(2x) = 3
-----
Graphing I get x = 67.73.. degrees = 1.182.. radians
===============
