Can the foci be on the ellipse? |
|
Answer» Answer: Yes Step-by-step explanation: An ellipse has two FOCUS points. One focus, two foci. The foci always lie on the major (longest) axis, spaced equally each side of the center. If the major axis and minor axis are the same length, the figure is a circle and both foci are at the center. Remember the two PATTERNS for an ellipse: Each ellipse has two foci (PLURAL of focus) as shown in the picture here: As you can see, c is the distance from the center to a focus. We can find the value of c by using the FORMULA c2 = a2 - B2. |

if theta =30° verify the following :- (a) cos 3 theta° = 4 cos ^3 theta - 3 cos theta (B) sin 3 theta° = 3 sin theta - 4 sin ^3 theta PROPER ANSWER=BRAINLIEST |
Answer» Solution :-I m assume theta = x = 30° (a) cos3x = 4cos³x - 3cosx PUTTING x = 30° both SIDES we get, → COS(3*30°) = 4cos³30° - 3cosx → cos90° = 4cos³30° - 3cosx values :-
Putting values both sides Now, → 0 = 4(√3/2)³ - 3(√3/2) → 0 = 4(3√3/8) - (3√3/2) → 0 = (12√3/8) - (3√3/2) → 0 = (3√3/2) - (3√3/2) → 0 = 0 (Verified) . _________________(B) sin3x = 3sinx - 4sin³x Putting x = 30° both sides we get, → sin(3*30°) = 3sinx - 4sin³30° → sin90° = 3sin30° - 4sin³30° values :-
Putting values both sides Now, → 1 = 3(1/2) - 4(1/2)³ → 1 = (3/2) - 4(1/8) → 1 = (3/2) - (1/2) → 1 = (3 - 1)/2 → 1 = (2/2) → 1 = 1 (Verified.) _________________________ |
