This week did not seem like it was too bad. What I'm thinking is that as long as I remember the formulas I should do pretty good. The exam on the other hand was very difficult for me, I completely bombed it. Here's what I really understood this week though.
Notes:
To find radians:
Notes:
To find radians:
radians = degrees x pi/180
To find degrees:
degrees = radians x 180/pi
Ex:
360 degrees, convert to radians
360 x π/180 = 360π/ 180 = π/2Convert π/10 to degrees.
π/10 x 180/π = 18 degrees
The only thing I am a little hazy on is the minutes and seconds thing. Knowing me I probably just wasn't paying attention for that part of the lesson

Finding both minutes and seconds isnt a hard task
ReplyDeletehere are some sinple notes that should help
To find minutes
multiply what is behind the decimal by 60
and take whole number as minutes'
To find seconds
multiply what is behind the decimal of minutes by 60
thenmultiply whats behind that decimal by 3600 to get seconds'
SOMETHINGS YOU NEED TO KEEP IN MIND ARE
((***Remember to always ues exact answers))
((*** Remember to never plug pi into calculator, instead use the pi button on calculator)
Angles:
ReplyDelete~measured in degrees (°), minutes ('), and seconds (")
~to find minutes multiply what is behind the decimal by 60
~to find seconds multiply what is behind decimal of minutes by 60; divide by 3600 to get decimal
Example:
Convert to degrees, minutes, & seconds - 25.52°
25(.52 x 60)'
25°31'(.2 x 60)"
25°31'12"
