To ease your live re write each one by using sin, cos, tan, knowing well that:
cscx = 1/sin x ( sin of an angle = opposite side/hypotenuse(23)
secx = 1/cos x (cos of an angle = adjacent side/hypotenuse(23)
cotx = 1/tanx (tan of an angle = opposite side/adjacent side)
Work it out & if you have difficulties do let me know

3/6=1/2 pound flour per dollar
