(a) Using integration, find I = A - sinh (1 ) do dx (b) Using Simpson's rule with six strips, estimate I = hi sinh|1 (1-0). dx. 6 3. Using integration by parts, find where f(x) = 3. f(x)=sin(4) dr 2 Hint: you can use f(x) = 3 to find the constant of integration. 4. Using integration, find I = x+18x+64 x+10x+24 dx. Hint: Express I as 1+ ax+b x+10x+24 where a and b are to be determined. 5. Hand sketch the graphs f(x) = x + 5x + 6 and g(x) = x- 7x+6 on a single set of axes. Provide all working to identify the intercepts, stationary points, and the points where the two graphs intersect. 6. Find the area between the curves f(x) = [-3,4]. x+5x+6 and g(x) = x- 7x+6 on the interval
