Step-by-step explanation:
Tan
tan
(3π) = Undefined
2
Just remember that, the periodicity of tan function is π.
Tan tan
(3π)
2
Break down the angle inside the function by applying the fraction rule
a+b = a +b
c. c. c as: = tan (2π + π )
2
Simply: = tan (π+π)
2
As stated above,
tan (π+x)=tan(x) we get: = tan( π)

I got it right on the test
Answer:
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces
so
![SA=b^2+4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3Db%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have
substitute
![SA=1^2+4[\frac{1}{2}(1)(2)]](https://tex.z-dn.net/?f=SA%3D1%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%281%29%282%29%5D)
Answer: 84 over 25 is 3.36 as your answer
