The three main trig functions are sine (written as sin), cosine (written as cos), and tangent (written as tan).
Sine of an angle = the length of the side opposite (aka across) the angle / the length of the hypotenuse
Cosine of an angle = the length of the side adjacent (aka the side next to which isn't the hypotenuse) to the angle / the length of the hypotenuse
Tangent of an angle = the length of the side opposite of the angle / the length of the side adjacent to the angle.
The acronym to remember this is SOHCAHTOA
SOH | CAH | TOA
SOH means sin(x) = opposite/hypotenuse
CAH means cos(x) = adjacent/hypotenuse
TOA means tan(x)= opposite/adjacent
cosB = length of adjacent side/length of hypotenuse = 7/25
tanB = length of opposite/length of adjacent = 24/7
sinB = length of opposite/length of hypotenuse = 24/25
Answer:
4/6
Step-by-step explanation:
Given dV/dt , find dh/dt.
Use volume formula for cone.
Define radius in terms of height.
Differentiate with respect to 't'.
Sub in given values, dV/dt = 12, h=2.
Solve for dh/dt.
Answer:
a is greater by 25
Step-by-step explanation:
if a=100
then,100-50=50-25=25
so same way= a is greater by 25
(-14/3)/12 = <span>-0.38888888888
0.38 = 38% or 38/100 </span>
