Question

5) Evaluate each of the following: i) sin30° + cos 45° + tan180° ii) cosec45° + cot 45° + tan0° iii) sin 30° x cos 45º x tan360°​

Answer 1

Answer:

(i) sin 30=1/2

cos 45=1/√2

tan 180=sin 180/cos 180=0/-1=0

adding all we get,

1/2+1√2+0=2+√2/2√2=1/2=0.5

(ii) cosec45+cot45+tan0

√2+1+0

=1+√2

(iii) sin 30 = 1/2

cos 45 = 1/root 2

tan 360 =0

therefore ans= 0
