sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
6 is the GCF because 6x3 equals 18 and 6x2 equals 12
Step-by-step explanation:
5^5•5 = 5^3
y^2/y= y^1 =y
a^2•a^3•a= a^6
b^5/b^7= b^-2
y^5/y^4=y
m^3•m^5•m^2=m^10
