6. If there are the following definitions: int a [10] = {1,2,3,4,5,6,7,8,9,10}, * P = & A [7]; then what is the value of the expression * P +?

The general expression of angle (including a) with the same terminal edge as angle a

A + 2pai * n (n is a positive integer)

If the terminal edges of angles α and β are the same, then there must be ()
If the terminal edges of angles α and β are the same, then there must be ()
A、α+β=180°
B、α+β=0°
C、α-β=k360°,k∈Z
D、α+β=k360°,k∈Z
PS: (I know why to say why there is an additional score

C、α-β=k*360°,k∈Z
Rotate 360 degrees. End edges coincide

In the triangle ABC, we know that BC = 3, angle a = 3 / π, let the inner angle B = x, the perimeter of the triangle ABC is f (x) (1), and find the expression of F (x),
(2) When what is the value of X, f (x) is the maximum, and the maximum value of F (x) is obtained

The angle A should be π / 3
According to the sine law of triangles, there are
BC/sinA = AC/sinB = AB/sinC
So AC = 2 √ 3xsinb, ab = 2 √ 3xsinc
B=x,c=π-A-B=2π/3-x
So perimeter f (x) = AB + BC + AC = 3 + 2 √ 3x (SiNx + sin (2 π / 3-x))
From the sum difference product formula
f(x)=3+2√3X2Xsin(π/3)cos(π/3-x)
=3 + 6xcos (π / 3-x)
2）
When x = π / 3, cos (π / 3-x) = 1, then f (x) is the largest
F (x) = 3 + 6 = 9

Given a triangle side 5.5 an angle 50 degree formula

a/sina=b/sinb=c/sinc

The general expression of the angle of the end edge on the coordinate axis

X-axis positive half axis: 360K (k is an integer)
Y-axis positive half axis: 90 + 360K (k is an integer)
X-axis negative half axis: 180 + 360K (k is an integer)
Y-axis negative half axis: 270 + 360K (k is an integer)
