If A is Acute and sin A= 2x/3, determine the value of the remaining functions
cos%28A%29=sqrt%281-sin%5E2%28A%29%29
cos%28A%29=sqrt%281-4x%5E2%2F9%29
cos%28A%29=sqrt%28%289-4x%5E2%29%2F9%29=sqrt%289-4x%5E2%29%2F3
cosA=√(9-4x^2)/3
tanA=sinA/cosA=2x/√(9-4x^2)
cscA=3/2x
secA=3/√(9-4x^2)
cotA=√(9-4x^2)/2x
