Why does inverse sin,cos or tan of numbers have multiple answers

When told to find angles when equations are involving sin,cos or tan at a level a range will be provided. You have to find all the angles within the given range. Multiple angles will be found as there will be a symmetry of graph answer (draw sine,cos and tan graph and explain) and a repeating cycle answer (draw sine and cos graph and explain)
