Answer:

Line passing through (3,0)\ and\ (0,-3).

Graph is attached.

Step-by-step explanation:

y-intercept:

substitute\ x=0\\\\y=0-3\\\\y=-3\\\\Hence\ this\ line\ passes\ through\ (0,-3)

x-intercept:

Substitute\ y=0\\\\0=x-3\\\\x=3\\\\Hence\ this\ line\ passes\ through\ (3,0)

Sketch a line passing through (3,0)\ and\ (0,-3).

Graph is attached.

Estimate the error if t6 (trapeziod rule with n=6) was used to calculate ∫30cos(2x)dx.
Hunter-Best [27]
The error bound for a trapezoid rule is given with this formula:
|E_t|\leq\frac{K(b-a)^3}{12n^2}
Where n is the number of points we used in the approximation, a and b are starting and ending point of an integral, and K is the number such that:
|f''(x)|\leq K
In order to find K we must find the second derivative of our function:
f(x)=30\cos(2x)\\ f'(x)=-60\sin(2x)\\ f''(x)=-120\cos(2x)
From this, we can see that our K is 120. This is the amplitude of this periodic function.
Now we can calculate the error bound:
E_t|\leq\frac{120(b-a)^3}{12\cdot6^2}=\frac{120}{432}(a-b)^3
Since you did not specify the interval of integration I cannot compute the final error bound. You can simply plug in the numbers to get the answer.
