Proofs in Trigonometric Identities Practice : Scaffolded with Drag n Drop
This activity contains 13 questions involving trigonometric identities that need to be proved.
Drag each line of trigonometric expressions from the white space to the space below the question, in the correct order as you attempt to prove that the left hand side equals to the right hand side of the identity presented.
Notation : sin(2x) is sin 2x
cos2(3x) is cos2 3x [which is (cos 3x)2 ]
csc(x) is cosec x [ which is cosecant x]
