More Steps

Evaluate
tan(30e2grs)tan(24e2grs)
Use tant=costsint to transform the expression
cos(30e2grs)sin(30e2grs)×tan(24e2grs)
Use tant=costsint to transform the expression
cos(30e2grs)sin(30e2grs)×cos(24e2grs)sin(24e2grs)
Multiply the terms
cos(30e2grs)cos(24e2grs)sin(30e2grs)sin(24e2grs)
cos(30e2grs)cos(24e2grs)sin(30e2grs)sin(24e2grs)120
Multiply by the reciprocal
120×sin(30e2grs)sin(24e2grs)cos(30e2grs)cos(24e2grs)
Multiply the terms
sin(30e2grs)sin(24e2grs)120cos(30e2grs)cos(24e2grs)
Use sin(t)cos(t)=cot(t) to transform the expression
sin(24e2grs)cos(24e2grs)×120cot(30e2grs)
Solution
