  • Whats up dudes! My names Saad the Skater, and today im here to break some skating records! Lets go to the skatepark and do it!
  • But first, let me try and break the record for the farthest distance horizontally jumping over a fence!
  • WOO-HOOO!
  • I know that the fence is 3 feet, and my fitness watch said I had a declination at an angle of 50 degrees, but I don't know the feet. Meaning we can do cos (50°) = 3/x, which becomes 3/cos(50°) which equals 4.66 feet, meaning that the horizontal distacnce I traveled was only 4.66 feet. That means I didn't break the record.
  • AW MAN!
  • 3 feet
  • 50°
  • Woah, that trick was insane, but now we have to see if we broke the record, which is 5 feet.
  • WOOOO-HOOOO!!
  • 8 feet
  • 55°
  • Now I am going to try and break the record for tallest ramp skated down! However, I am not sure if this ramp is big enough, and it is too tall for me to measure, so I have to use math. (The current record is 10 feet)
  • Its a bummer that we werent able to get that last trick, but we still have a few more to go!
  • So I was only able to measure two things, the angle of elevation from the bottom which is 55°, as well as the length of the base on the bottom, which is 8 feet. However, I can find the height with just these two things. I can do tan (55°) = x/8 which would then equal 8 * tan (55°), which equals 11.43 feet. Meaning that I broke the record! WOO-HOO!
  • (note: ramp not visualized to scale)
  • All I need to do is find the inverse tangent of this triangle, which would be: tan^-1 (3/6) which equals 26.56°! And since the current records is 30° I broke the record!
  • However, there is a problem, I don't now the angle, but I can use math for that! I was able to measure the height of the ramp as 6 feet, and the length of the bottom base is 3 feet.
  • Alright guys, this is going to be the last trick of the day, and in this trick, I am going to ride down the steepest ramp in the world.
  • 3 feet
  • YIPPIE!!
  • 6 feet
  • That was a great skate sesh! I was able to break 2/3 records I tried today, and I'm pretty proud of that! Now I gotta go, see ya later!
