Estimating the six trig functions
Provide your estimate for each of the six trig functions for the given angle. You should estimate each one directly from the diagram. For example, don't find the value of [math]tangent\left(\theta\right)[/math] and then use that to compute the value of [math]cotangent\left(\theta\right)[/math].
