Please Help! :3

Answer 1

What do u Need help with

Answer 2

If \[f(x)=\frac{ 3 }{ 2}\sqrt{1+\tan x} \times \sec ^{2} x\] then find f(0)

Answer 3

...What math are you in?

Answer 4

do you know how to determine the tangent of an angle

Answer 5

If you look at the unit circle of radius 1, the tangent is y/x for any point on the circle

Answer 6

of the angle is zero degrees, you are on the +x axis, and y/x will be zero, so tangent of zero is 0...

Answer 7

secant , is 1/cos(x),

any point on the circle is (x , y ) = (cos , sin )

the x coordinate for zero degrees (+x axis) , is 1

Answer 8

put those values in and solve... f(0)
