Show that the centre of the circle with equation:
x^2 + y^2 = 6x + 8y is (3,4) and find the radius
Thanks =]
Hey i have two problems that i am stuck on
1) Solve the following quation for 0 < theta < 180
(i will use x for theta, i know how to solve using the ASTC graph however i cannot rearrange this)
Cos^2(x) / Sinx + Sin^2(x)= 2
We have been told earlier that this is equal to 1-sinx/sinx
Hello, acid_rainbow!
1) Solve the following equation for
Cos^2(x) / Sinx + Sin^2(x) = 2 . . . . What is in the denominator?
We have been told earlier that this is equal to . . . . Ah, this helps!
We have: .
which simplifies to: .
Then: . not in the interval
And: .
