these are a couple more math problems im having trouble with. if you can help me i would appreciate it. if you could just put the number of the problem your helping me with that would be great 1)simplify -3sin^(5)x - 3sin^(3)x cos^(2)x 2.)simplify 2cot^(2)x -3cotx - 9 / cot^(2)x - 9 3.)simplify 5cos^(4)x - 5sin^(4)x and write in terms of cos x. 4.)simplify tan^(2)x + (1 + sec x)^2 write in terms of sec x.
