Question

tan9°-tan27°-tan63°+tan81° ka maan kya hoga?
(a) 1. (b) 2. (3) 3. (4) 4.​

Answer 1

Answer:

Step-by-step explanation:

tan(A+B)=(tanA + tanB)/1-tanAtanB

tan(9+81)=tan90=tan9+tan81/1-tan9tan81

tan(27+63)=tan90=tan27+tan63/1-tan27tan63

tan90(1-tan9tan81)-tan90(1-tan27tan63)

tan90(tan27tan63-tan9tan81)=infinity(as tan 90=infinty)
