sec(x)=9

sec (x) = 9

x = 1.45945 \dots + 2 πn, x = 2 π - 1.45945 \dots + 2 πn

Solution steps

sec (x) = 9

Apply trig inverse properties

x = arcsec (9) + 2 πn, x = 2 π - arcsec (9) + 2 πn

Show solutions in decimal form

x = 1.45945 \dots + 2 πn, x = 2 π - 1.45945 \dots + 2 πn

cot (x + 1) = 0

cot^{2} (x) = \frac{1 + sin ( x )}{1 + cos ( x )}

0.7 sin (3 π t) - 3 π cos (3 π t) = 0

sin (θ) = \frac{8}{15}

cos (x) cot (x) cos (x) = 0, 0 \leq x \leq 2 π
