Answer:
Sin (4.25π)= 0.7071
Cos(4.25π)= 0.7071
Tan(4.25π)= 1
Step-by-step explanation:
[tex]\pi=180º (half circumference)\\ 2\pi= 360º (complete circumference)\\ 4\pi= 720º (2 complete cincumference\\ 4.25\pi= 720º + 45º (2 complete circumference + 45º)[/tex]
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.
So:
[tex]Sin (45º) = \frac{\sqrt{2} }{2}\\Cos (45º) = \frac{\sqrt{2} }{2}\\ Tan(45º) = 1[/tex]
