You can put this solution on YOUR website!
sin%5E2%28x%29%2B+cos%28x%29+%2B1+=0
%281-cos%5E2%28x%29%29%2B+cos%28x%29+%2B1+=0
-cos%5E2%28x%29%2Bcos%28x%29%2B2=0
cos%5E2%28x%29-cos%28x%29-2=0
u%5E2-u-2=0
%28u-2%29%28u%2B1%29=0
Two possible solutions:
u-2=0
u=2
cos%28x%29=2
No solution here.
u%2B1=0
u=-1
cos%28x%29=-1
x=pi
However since your solution has to lie with [0,2], there is no solution.
