Secant is 1 over cosine and cosine 0 equals 1.
1. Any number to the power of 0 is 1.
Assuming that 4x2+2x = 0: 2x (2x+1) = 0 2x = 0 or 2x+1 = 0 x = 0 or -1/2
The period is the length of x over which the equation repeats itself. In this case, y=sin x delivers y=0 at x=0 at a gradient of 1. y next equals 0 when x equals pi, but at this point the gradient is minus 1. y next equals 0 when x equals 2pi, and at this point the gradient is 1 again. Therefore the period of y=sinx is 2pi.
x = 1, y = 0
sec x = 1/cos x sec x cos x = [1/cos x] [cos x] = 1
1/45 sec or 0.023 sec
120 sec. There are 60 in 1 min. what I do is erase the 0 from the 60 and add 6+6 which equals 12 and than put the 0 back which makes it 120 again
2sinx+1 equals 0
1-0
Secant x= 1/cosx So if cos x=1 ,we know that x=0 degrees ( or radians), so secant x is 1/cos (0)=1/1=1
1 nanosecond = 10-9 sec = 0.000000001 sec = 1 billionth of a sec. (Roughly the time it takes light/radio to travel one foot.)
Everything to the power of 0 equals 1.
No. ' 1 ' is not equal to ' 0 '.
19.2m/min calculation 60 sec/1 min * 32 cm/sec * 1 m/100cm
sin(0) = 0, sin(90) = 1, sin(180) = 0, sin (270) = -1 cos(0) = 1, cos(90) = 0, cos(180) = -1, cos (270) = 0 tan(0) = 0, tan (180) = 0. cosec(90) = 1, cosec(270) = -1 sec(0) = 1, sec(180) = -1 cot(90)= 0, cot(270) = 0 The rest of them: tan(90), tan (270) cosec(0), cosec(180) sec(90), sec(270) cot(0), cot(180) are not defined since they entail division by zero.
sec + tan = cos /(1 + sin) sec and tan are defined so cos is non-zero. 1/cos + sin/cos = cos/(1 + sin) (1 + sin)/cos = cos/(1 + sin) cross-multiplying, (1 + sin)2 = cos2 (1 + sin)2 = 1 - sin2 1 + 2sin + sin2 = 1 - sin2 2sin2 + 2sin = 0 sin2 + sin = 0 sin(sin + 1) = 0 so sin = 0 or sin = -1 But sin = -1 implies that cos = 0 and cos is non-zero. Therefore sin = 0 or the solutions are k*pi radians where k is an integer.
If it's 1 +-1 =0
