Allemande135 Posted September 16, 2018 Report Share Posted September 16, 2018 Is finding the derivative of trigonometric/circular functions, like the sine and cosine functions, part of the Math SL syllabus? Is this the level of Math SL or is it more advanced? I'm thinking of doing this in my calculations for my IA. Would it work? Reply Link to post Share on other sites More sharing options...
Nomenclature Posted September 17, 2018 Report Share Posted September 17, 2018 Yes, but their derivatives are just cosin and -sin. Maybe I don't understand what you want to do? Reply Link to post Share on other sites More sharing options...
Vighnesh Posted September 19, 2018 Report Share Posted September 19, 2018 You could use the first principles rule to prove the derivates, but I am not sure what is there in the Math SL syllabus, so I think that it would be better if you check with your teacher about this.

Lucky- Posted September 19, 2018 Report Share Posted September 19, 2018 Dont really understadn if u try to use derivative of sin in ur ia or applying derivative in your ia. If u are proving the derivative of anything, then IT DONT WORK, math ia should NOT foucs on proving something (say proving an equation) instead math ia should focus on applying math to real life. If u are using derivative of sin or other trig thingy, then its totally fine or even partially adavnced given you are a math sl. Reply Link to post Share on other sites More sharing options...
