→ x = 4y + 3 equation 1st
→ y = -2x -3 equation 2nd .
Now putting the value of x from first equation to second equation.
→ y = -2(4y +3 ) -3
→ y = -8y - 6 - 3
→ y + 8y = -9
→ 9y = -9
→ y = -1
Now putting the value of y in equation first .
→ x = 4(-1) + 3
→ x = -4 + 3
→ x = -1
Now multiply and X and y.
→ x.y = -1(-1)
→ x.y = 1 .
That zero with the line through it is theta I believe.
Use the FOIL method to multiply the numerator and denominator out. Then use your Trig Identities (probably in your course content or notes already but you can also google them) to see what it is equal to.
What do you need help with?
Answer:
Step-by-step explanation:
To find the values of the angle which makes maximum r you use the derivative of r
If you equals this derivative to zero you obtain the value of the angle:
However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.
hence, the answer is:
