Let the propositional function C (f,a) mean "The function f is continuous at the point a," and let the propositional function of D(f,a) mean "The function f is differentiable at the point a" Using these symbols together with logical symbols, express the following statements.

Best ResponseYou've already chosen the best response.2Neither the tangent function nor the secant function is continuous at pi/2. Either a>0 or the natural logarithm function is not differentiable at a. The absolute value function is continuous at 0, but not differentiable at 0.

Best ResponseYou've already chosen the best response.2so for the first one I got that the sentence is related to C f(a,) because the functions are tangent and secant. I should write it as ~C(f,a) but is just ~C(f,a)?

Best ResponseYou've already chosen the best response.2Second one. D(f,a) related. it says that either a>0 or the natural logarithm function is not differential at a. if I didn't have the c(f,a) d(f,a) required I would easily put my P as a>0 and Q that long sentence and that would be P V Q.

Best ResponseYou've already chosen the best response.2Third one is again D(f,a) related. The absolute value function is continuous at 0, but not differentiable at 0. with my p = absolute value function is continuous at 0 q = not differentiable at 0 this is not an implies or biconditional.

Best ResponseYou've already chosen the best response.2P ^ Q but that would read as The absolute value function is continuous at 0, [and] not differentiable at 0.

Best ResponseYou've already chosen the best response.2but thing is how to apply the C(f,a) and D(f,a) in this?

Best ResponseYou've already chosen the best response.0For second question : Either a>0 or the natural logarithm function is not differentiable at a. (a >0) V ~D(ln, a <= 0)

Best ResponseYou've already chosen the best response.2OH OF COURSE! *facepalm* we have to apply the f a in the C or D

Best ResponseYou've already chosen the best response.2The absolute value function is continuous at 0, but not differentiable at 0. The ORIGINAL D(f,a) states "The function f is differentiable at the point a" F not differentiable at 0 . . . hmm there's no point a

Best ResponseYou've already chosen the best response.2the first one for C(f,a) f would be neither tangent nor secant a is continous at pi/2

Best ResponseYou've already chosen the best response.0The absolute value function is continuous at 0, but not differentiable at 0. C(f, 0) ^ ~D(f, 0)

Best ResponseYou've already chosen the best response.0you want to translate the given statements to boolean symbols. thats all right ?

Best ResponseYou've already chosen the best response.2errr it did say that I have to use those special symbols... if I didn't have to, I can easily see the P and Q 's

Best ResponseYou've already chosen the best response.2so all of C(f,a) is negated on this.

Best ResponseYou've already chosen the best response.2Neither the tangent function nor the secant function is continuous at pi/2 is purely a negative C (f,a) for f being tangent function nor secant function and a continuous at pi/2

Best ResponseYou've already chosen the best response.0First one : Neither the tangent function nor the secant function is continuous at pi/2 is ~C(tan, pi/2) ^ ~C(sec, pi/2)

Best ResponseYou've already chosen the best response.2well I quickly saw the first one as a double negative. no no it did say to use C f,a and D f,a Which I sort of seen. except the last one was a tad tricky

Best ResponseYou've already chosen the best response.0for me, first and last are easy. middle one is tricky as we need to think a bit
