This is a Smart Worksheet on Trig identities and trig equations. The idea here is that you pick a problem to try and then click on the video solutions.
There's a host of other useful tools as well - trig equation solvers both general and in a specified range and a trig identities solver which provides a number of alternatives to the expression entered, So if you have problems of your own that need checking then look no further.
There's also an email? and any questions that you have can be submitted as well as a pdf version of the worksheet so that you can work on the problems independently if you prefer.
So all the best then guys and if you have any suggestions or ideas for new smart worksheets then just give us a buzz and send us an email.
