Question

ii)Complete the following activity to find the values of cos 600 × cos 300 + sin 600 × sin 300 = 1 2 × + 3 2 × 1 2 = + 3 4 = 3 4​

Answer 1

Answer:

sin2600cos2300+tan450cos600sin300

=sin2600sin2600+(1)cos2600

=sin4600+cos2600

Substituting the values of sin600 and cos600 we get

(23)4+(21)2

=169+41

=1613
