sin^2 + cos^2 = 1 1 + cot^2 = csc^2 cot^2 = csc^2 - 1

ok

or simply draw out the triangle and solve for cot = x/y

arccos relates a ratio to an angle ... its the reverse, or invers, of cosine
amistre64
  • amistre64
for example: cos(45) = 1/sqrt(2) therefore 45 = arccos(1/sqrt(2))

so arccos equals the sin
amistre64
  • amistre64
trig (angle) = ratio angle = arctrig (ratio) if you know the ratio, you can rebuild the triangle no, sin and arccos are not equivalent function

but would it be cot(12/13)
amistre64
  • amistre64
you are confusing angles and ratios at the moment
