In this video, I take you through the topic derivatives of trigonometrical functions.
You will be able to learn how to differentiate trigonometrical functions
-from first principles,
-using chain rule,
-using product formula,
-using quotient formula.
You will also be able to learn how to differentiate inverse trigonometrical functions.
Worked examples from U.A.C.E UNEB Question Bank have also been included in this video.
This video is suitable to A-level students in Senior Five and Six offering Principle Mathematics as part of their combination. E.g. (PCM, BCM, PEM, PMT, PMA, MEG, MET, MEF, MEA e.t.c.)
