Answer 4

derivative of sec x is sec x tan x
have fun with the product rule... or you could use the quotient rule if you feel like banging your head into a wall.

Answer 5

tanx=(sin x divided by cos x) rite...
so when u differentiate (sin x over cos x) you get
\[\left((\cos ^{2}x + \sin^{2}x)\div \cos^{2}x) \right) \]
and as \[(\cos ^{2}x + \sin^{2}x)=1\]
it equals
\[\left((1)\div \cos^{2}x) \right) \]
which equals
\[\sec ^{2}x\]
