(cot^2 betta)/(csc betta)=csc betta-sin betta

cos betta+ sin betta tan betta= sec betta

Determine the domain and the range of the relation
{(2,0),(30,-5),(34,0),(2,3),(54,3)}

sin(x)^2=2cos(x)+2

sin(x)=csc(x)

2sinxcosx+sinx-2cosx-1=0

solve in interval [0,2)

4x/x-3=2+12/x-3

a student stands a certain distance from a building and measures the angle to the top of the building 18.8. the student then walks 24n straight towards the build and measures the angle to the top of the building as 20.2 what is the height of the building

If the angle of elevation of the fifth floor of the building from a point 14.5 meters from its bases is 42 degree, find the height of the floor of the building?

sin3A+sin2A-sinA = 4sinAcosA/2cos3A/2
