Question

Should there be a decimal trig functions? ex...... cotA = .29

Answer 1

why not

cot = 1/tan

so

cot(a) = 0.29 which means tan(A) = 100/29

Answer 2

but the question doesn't make a lot of sense unless you are talking about exact values

Answer 3

\(\bf cot(A) = 0.29\implies \cfrac{1}{tan(A)} = 0.29\implies \cfrac{1}{0.29}= tan(A)\)

Answer 4

and that gives you a valid angle

Answer 5

what's the context?
