Solution:
Consider the curves,
y=sin‌2‌x And,
y=cos‌2‌x Therefore,
sin‌2‌x=cos‌2‌x tan‌2‌x=1 2x= x= Therefore,
y=sin‌2‌x =sin‌ = And,
y=cos‌2‌x =cos‌ = Therefore,
m1=()(.) =2‌cos‌2‌x =2‌cos‌ =√2 And,
m2=()(,) =−2‌sin‌2‌x =−2‌sin‌ =−√2 The angle between the curve is given by,
tan−1() =tan−1() =tan−1() =tan−1(2√2)
