    Collinear Vector Help: Finding the Value of p for Collinearity | Origin O

    One more question. a) The vector \displaystyle \overrightarrow{OA} has magnitude 100 and has the same direction as \displaystyle \left(\begin{array}{cc}7\\24\end{array}\right). Express \displaystyle \overrightarrow{OA} as a column vector. b) The vector \displaystyle \overrightarrow{OB} is...

    Collinear Vector Help: Finding the Value of p for Collinearity | Origin O

    The position vectors of A, B and C relative to an origin O are -I+pj, 5i+9j & 6i+8j respectively. Determine the value of p for which A, B & C are collinear.

    How do you change the magnitude of a vector?

    Thank you.

    How do you change the magnitude of a vector?

    Three vectors a, b and c are such that a = i + 3j, b = 2i + j and c = i + 13j. Find (i) the vector which is parallel to a + b and of magnitude 20 units. (ii) the value of p and of q for which pa + qb = c I need help in both parts.

    Finding the Angles: A Trigonometric Problem

    Find all the angles from 0^{\circ} to 360^{\circ} inclusive which satisfy the equation $ \tan(x-30^{\circ}) - \tan 50^{\circ} = 0

    High School Brightest Explosion Ever Observed

    No (I wish we could have). http://story.news.yahoo.com/news?tmpl=story&cid=570&ncid=753&e=3&u=/nm/20050218/sc_nm/space_explosion_dc

    Find x-Coordinates of Points on y=3x/(2x-3) with Normal Parallel to 9y=4x+3

    Yes, apparently I found a way. Find the derivative Gradient of 9y=4x+3 and normal => 4/9 Gradient of the tangent line => -9/4 Set -9/4 = derivative You know, its too coincidental that you got the same question as me? :rolleyes:
