The character Bosola is a man who has suffered unfairly at the hands of those he has worked for, leading him to become a man who can no longer trust those around him and leaving him with very little compa...

5 = a(3x+2) + b(x-1), x = 1, 5 = a(3+2) +b (1-1), 5 = a(5) + b(0), 5 = 5a, a = 1, x = -2/3, 5 = a(-2+2) + b(-(2/3)-1), 5 = a(0) + b(-5/3), 5 = -5b/3, b = -3, Therefore: 5/[(x-1)(3x+2)] = 1/(x-1) -3/(3...

Nora treatment of her father - leaving him on his deathbed - contrasts highlight with Mrs Linde's treatment, as she chose to care for her sick parent. Nora's treatment is reflective of her childlike natur...

You will have to use the Product Rule. The Product rule: when y=f(x)g(x), then dy/dx=f'(x)g(x)+f(x)g'(x). In this example, f(x)=sin(x) and g(x)=cos(x). Hence f'(x)=cos(x) and g'(x)=-sin(x). Using these an...
