MathYou need to find value for which cos equals `sqrt3/2 ` . Using a unit circle, it can be determined that the answer is `(5pi)/6 `

MathThis asks you what value of sin equals `sqrt2/2 ` (`sinx=sqrt2/2 ` . Remember that sin is y values . Using a unit circle, you can determine that the answer is `pi/4 ` .

MathYou need to find value for which tan equals `sqrt3 ` . Using a unit circle, it can be determined that the answer is `pi/3 `

MathYou need to find value for which tan equals `sqrt3 ` . Using a unit circle, it can be determined that the answer is `pi/3 `

MathYou need to find value for which cos equals `1/2 ` . Using a unit circle, it can be determined that the answer is ` (2pi)/3 `

MathYou need to find value for which sin equals `sqrt2/2 ` . Using a unit circle, it can be determined that the answer is `pi/4 `

MathYou need to find value for which sin equals `sqrt3/2 ` . Using a unit circle, it can be determined that the answer is `pi/3 `

MathYou need to find value for which tan equals `sqrt3/3 ` . Using a unit circle, it can be determined that the answer is `pi/6 `

MathGraph: It approaches zero, but it never gets there (limit does not exist).

MathGraph, It looks like y approaches 0 when x approaches 0, but x=0 is undefined.

MathIt is even. `cosx=cos(0x) ` `cos(0x)=sin0sinx+cos0cosx=cosx ` Therefore, `cos ` is even `sec(x)=1/cosx ` This equals `1/cosx=secx ` Therefore, `sec ` is even

MathThe graph of the functionis symmetric about origin.So it is an odd function. f(x)=tanx f(x)=tan(x) =tanx =f(x). f(x)=f(x).So the function is odd.

MathClearly at x=0 the function is not defined.As `xgt0 ,ygtoo`
