Hello Student,
Please find answer to your question below

The first question figure is not given and the question is incomplete.
Please rewrite your question so that I can provide you reasonable answer.
2)
f(x) = sinx - cosx
f(1) = sin1 - cos1
f(1) > 0
sin1 – cos1 > 0
sin1 > cos1
tan1 > 0
1 is lie between 0 and pi/2 the interval in which tanx is positive.
Hence, proved.
