Question

URGENTE!!!!!

defina o domínio:

a) y = sec(x/3 - π/4)

b) y = sec(x/4 - 180)​

Answer 1

Resposta:

y = 1/cos(x°+30°)

X° can be converted to radians 

 

X°= pi times x÷180 

Therefore the derivative is 

dy/dx=cos(pi times x ÷180).pi/180

dy/dx= [-1/cos^2 (x°+30°) ](- sin(x°+30°) ) (¶/180)

dy/dx = ¶/180sin(x°+30°)/cos(x°+30°)*cos(x°+30°)

dy/dx = ¶/180 sec(x°+30°).tan(x°+30°)
