Answer:
Sin (4.25π)= 0.7071
Cos(4.25π)= 0.7071
Tan(4.25π)= 1
Step-by-step explanation:
Sin, Cos and Tan of 45º angle is the same with 1,2 or more circumferences.
So the result is the same for 45º angle.

<u>Complex Numbers</u>
They are expressed as the sum of a real part and an imaginary part:
Complex numbers can also be expressed in polar form:
Where r is the modulus of the complex number and θ is the argument.
The argument can be calculated by:
The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.
The complex number is given as:
Here: a=-3, b=-9
Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).
The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
