Question

If tan A =
4/3
then find the values of the following:
i) sin 2A
ii) cos 2A
iii) tan 2A
iv) cot 2A​

Answer 1

Answer:

tan = p/B

H² = p² + b²

H² = 4²+ 3²

H² = 16 +9

H² = 25

H = 5

i) 4/25

ii) 3/25

iii) 4/3

iv) 3/4

Answer 2

Answer:

i)Sin 2A=8/10

ii)Cos 2A=6/10

iii)tan 2A=8/6

iv)Cot 2A=6/8
