How to solve this ?? and explain it please :(
∫

+ Constant

Step-by-step explanation:

Step 1: Remove the common factor from the radicand

move the constant in front of the integral

Step 2: multiply integral by 1 - cosx

1 - is equivalent to by trig identities

Step 3: simplify the integral with the identity before using u-substitution

Step 4: Use U-Substitution

u = 1 - cosx

du = sinx dx,   dx =

Step 5: Integrate

Step 6: substitute original u value and solve for final answer

  + Constant

if you mean

then it's c. 8, -7/3

but if you mean

then it is

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
