1 answer:
Answer:
P(x, y) = (√3/2, -1/2)
Step-by-step explanation:
There are a few special angles whose trig functions are worthwhile to remember. The top half of the table in the second attachment shows these.
The first attachment shows a unit circle and coordinates of the points at these special angles. It is worthwhile to remember there are 2π radians in a circle, so -π/6 radians (your angle) corresponds to a positive angle of 11π/6 radians.
__
The coordinates of P are ...
P(x, y) = (√3/2, -1/2)
_____
<em>Additional comment</em>
The coordinates of any point at angle α on a unit circle are ...
(x, y) = (cos(α), sin(α))

Answer:
Step-by-step explanation:
The given equation is :
We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :
We know that, 4×4= 16 and 5×5 = 25
So,
So, the solution of the given equation is 4/5.
