    Synthesis 

    Which topic/s in class made an impact to you? Why?
    Yung mga related sa matrices(halos lahat pala) lalo na yung operations tapos RREF kasi sobrang nahirapan ako pero noong medyo na-gets ko na sobrang fulfilling. hehe. nag-enjoy rin ako kasi ang dami pala nilang applications :O parang everytime magpapakita ng example ng applications sa class napapanganga ako tapos lumalaki mata ko (kahit d halata)

    If you can summarize this course in one word or sentence, what would it be?
    This course is….challenging but very interesting. (Kung iisipin mo lang yung concepts siguro mahirap tapos boring pero dahil tinuro rin sa amin yung applications nila in real life, naging interesting)

    What would be your parting message to the class?
    Thank you for the fun semester! See you around 🙂

    Fourier Transform and Frequency Filters 

    Fourier transform allows us to smoothen or sharpen images using filters. An image is first converted from spatial to frequency domain (high components=edges; low components=smooth regions) using Fourier transform then it is multiplied with a filter function (lowpass, highpass, bandpass filter) in a pixel-by-pixel fashion, and converted back to spacial domain.
    For example, a lowpass filter will reduce high frequencies and retain low frequencies resulting to a smoother image.

    Sun-Moon Symmetry 

    “With the sun having a diameter of 1.4 million kilometers and the Moon having a diameter of a mere 3,474 kilometers, it seems almost impossible that the moon is able to block the sun’s light and give us around five solar eclipses every two years.How does it happen? Coincidentally, while the sun’s width is about four hundred times larger than that of the moon, the sun is also about four hundred times further away. The symmetry in this ratio makes the sun and the moon appear almost the same size when seen from Earth, and therefore makes it possible for the moon to block the sun when the two are aligned.”

    Vectors in Golf 

    “When you hit a golf ball, the direction of motion of the club head determines the direction of the force vector, which can be broken into two perpendicular components that determine the direction of motion of the ball and its spin.

    Golfers can use golf clubs with different club head angles to vary the vertical direction as well as the spin. They can also adjust the way they hit the ball to change angles and spin” (kaya pala nagpapalit sila ng golf club :O)
