know how to draw each graph. The 3 and sqrt (3) are the amplitude of the respective graph.
Since the question asked for the range of value for which the sine graph is greater than the cosine graph, deta has to be larger than or equal to 30deg AND less than or equal 90deg to be kept within the interval given by the question.
Hope you understand.
