Question

If Cota=m then Cosa is equal to what

Answer 1

Step-by-step explanation:

We will first express cosA in terms of cotA

cos A = 1 / sec A

= 1 / √(1 + tan^2 A)

= 1 / √(1 + 1/cot^2 A)

= 1 / √[(cot^2 A + 1)/cot^2 A)]

= 1 / √[(cot^2 A + 1)] / (cot A)

= (cot A) / √[(cot^2 A + 1)]

Now we know cot A = m

Substitute for it

We get :

m / √(m^2+1)
