i have a few questions.. :b

1. show that; tan(x)=sin^2(x)/1+cos^2(x)

2. In a triagnlle with the area 88m^2, is there a 75 degree angle, and a 65 degree angle, calculte the triangles longest side.

3. solve the equation sin^2(x)/2=cos(x)

and one more;

4. solve the equation cos^2(x)=sin(x)+1

i hope someone can help, i need this help within an hour :)!
