Given : 4Sin30 + tan48 . tan42 – 3tan45
To find: Value
Find:
We can solve the values individually then substitute it in trigonometry equation.
sin30 = 1/2
tan 48 = 1.11
tan 42 = 0.9
tan 45 = 1
Substituting values in the equation
= 4Sin30 + tan48 . tan42 – 3tan45
= 4x 1/2 + 1.11 . 0.9 – 3x1
= 2 + 0.999 - 3
= 2.999-3
= - 0.001
The answer to this equation is -0.001
