Question

Р
PS = SQ and 2Q is a right angle.
Determine (i) sin a, cosec a, sec a.
(ii) sec?a – tan? a

Answer 1

Answer:

Step-by-step explanation:

find the value of:

(i) sin 30o cos 30o

(ii) tan 30o tan 60o

(iii) cos2 60o + sin2 30o

(iv) cosec2 60o - tan2 30o

(v) sin2 30o + cos2 30o + cot2 45o

(vi) cos2 60o + sec2 30o + tan2 45o.
