Is the cosine function an odd function?
No. Cosine, along with sec, is an even function. The odd functions are sin, tan, csc, and cot. The reason for this is because is you take the opposite of the y-value for the cosine function, the overall value of the function is not affected.Take, for example, cos(60 degrees), which equals POSITIVE 1/2.If you flip it over the x-axis, making the y's negative, it becomes cos(-60 degrees), or cos(300 degrees). This equals POSITIVE 1/2.Now let's look at an odd function. For example, sin(30 degrees) equals POSITIVE 1/2. Now take the opposite of this.sin(-30 degrees), or sin(330 degrees), equals NEGATIVE 1/2. This is because it is found in the fourth quadrant, where the y's are negative. Sine of theta, by definition, is y divided by r. If y is negative, sine is negative.
If you were to travel through an angle of 8 degrees across the surface of the earth through how many kilometers would you have traveled?
It depends on your latitude. At the equator (0 degrees) a degree of longitude covers just over 111 km, so 8 degrees would be about 890 km. At 45 degrees of latitude, a degree of longitude covers just under 79 km, so 8 degress would be about 555 km. Check out the calculator in the related link. Enter the degrees of latitude and it gives the length of a degree at that point.
To convert 25 hours to minute you would use the ratio 1 hour over 60 minutes is that true or false?
That is true. 1/60 is the ratio. To convert 25 hours to minutes, you would multiply 25 by 60, which equals 1500 minutes.
1 over sin x equals what?
1/sin x = csc x
Explain why tan270 degrees is undefined?
Just as at 90 degrees, it goes to infinity. That is because tangent of angle is opposite side over adjacent side. The oppsoite side gets bigger and bigger after 45 dgerees ( and in your case then after 225 degrees) until it grows beyond all bounds at 270 degrees
What would be the value of x if x over 9 equals 1?
9
If Cosine x degrees equals 5 over 7 what is x?
Approx 44.4 degrees.
If x equals 4 and y equals 8 to 1 significant figure find the smallest value of x plus y?
If x equals 4 and y equals 8 to one significant figure thelowest value of x would be 3.49 (the nine is recurring and the lowest value of y would be 7.49 (the nine is recurring so the lowest over all value of the two would be 10.98 (the eight is recurring
What is the value sin x if cos x equals 2 over sqrt 5?
It would be 1 over square root 5.
Sin 46 degrees equals x over 14 What is x?
13.20
What is the value of 1 over 3 plus 1 over a equals 5 over 12?
1 over 3 plus 1 over 12 equals 5 over 12
What is 98.7F in Celsius?
98.7 F equals slightly over 37 degrees C
What is the value of x over 9 equals 1?
x=9
What is the value of x when x-8 over 3 equals 5x?
-1
What is six equals a over 4 plus two?
It is an equation and the value of a is 16
What is 7 equals x over 13?
It is an equation and the value of x is 91
X over 3 minus 1 over x equals 2 over 3?
It can do. Depends on the value of x.
