In the activity below, your task is to record down the sine, cosine and tangent of [math]\angle DAX[/math].[br][br]Set [math]\angle DAX=30^o,50^o[/math]or [math]80^o[/math][br]For each angle, modify the size of the triangle such that [math]AX[/math] is 3.3, 6 or 8 units respectively.
When the angle is fixed at [math]30^o[/math] and the length of [i]AX [/i]is set to 3.5, 6 and 8 units,[br]what do you notice about the sine, cosine and tangent of [math]\angle DAX[/math]?
They are unchanged for a given angle
