Given sin = 0.89, tan = 1.98:

Calculate other trig values

Calculate csc(x) given sin(x):

csc(x)  =  1
  sin(x)

csc(x)  =  1
  0.89

csc(x) = 1.123595505618

Calculate cot(x) given tan(x):

cot(x)  =  1
  tan(x)

cot(x)  =  1
  1.98

cot(x) = 0.50505050505051

Calculate cos(x)

tan(x)  =  sin(x)
  cos(x)

Cross multiplying, we get:

tan(x) x cos(x) = sin(x)

Divide each side by tan(x):

tan(x) x cos(x)
tan(x)
=
  
sin(x)
tan(x)

cos(x)  =  0.89
  1.98

cos(x) = 0.44949494949495

Calculate sec(x) given cos(x):

sec(x)  =  1
  cos(x)

sec(x)  =  1
  0.44949494949495

sec(x) = 2.2247191011236
