Sin(kx)=0=>x=0,π,...
∫0πsin(kx)dx=−1/kcos(kx)|π0=−1/k(cos(kπ)−cos(k∗0))
if k is odd then,=−1/k(−1−1)=−1/k(−2)=2/k
if k is even then,=−1/k(1−1)=0
Answer:
1 topping...
Next time, add some background information because people don't have the context necessary to solve the question. Hope this helps :)
Step-by-step explanation:
For number 1, you start at zero and go to the left since the four is negative four spaces. Then, you go to the right two spaces since the 2 is positive. Your answer is -2
For number 2, you start at zero and go left four spaces since it is negative and then go two more spaces to the left because it is negative again
