Math`arcsin(1/2) ` is the value whose `sin ` equals `1/2 ` . What angle has a sine equal to 1/2? `pi/6 `

MathYou need to find the value where the sin of some value give me 0 (`sinx=0 ` ). Using the unit circle, one can devise that the answer is `0 ` .

MathYou need to find what value of cos gives an answer of 1/2 (`cosx=1/2 ` ). Using a unit circle, one can find the answer to be `pi/3 ` .

MathEssentially, the question is asking what value of cos gives me 0 (`cosx=0 ` ). Using a unit circle, you can find the answer to be `pi/2 ` .

MathThis question is asking what value of tan will give me `sqrt3/3 ` (`tanx=sqrt3/3 ` ). Using a unit circle, you can determine that the answer is `pi/6 ` .

MathThis asks you what value of tan equals 1 (`tanx=1 ` ). Remember that tan is y/x. Using a unit circle, you can determine that the answer is `pi/4 ` .

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
