Description: Join three consequents. (Contributed by FL, 1-Aug-2009.)

Hypotheses

Ref	Expression
jca31.1	|- ( ph -> ps )
jca31.2	|- ( ph -> ch )
jca31.3	|- ( ph -> th )

Assertion

Ref	Expression
jca32	|- ( ph -> ( ps /\ ( ch /\ th ) ) )

Proof of Theorem jca32

Step	Hyp	Ref	Expression
1		jca31.1	. 2 |- ( ph -> ps )
2		jca31.2	. . 3 |- ( ph -> ch )
3		jca31.3	. . 3 |- ( ph -> th )
4	2, 3	jca 306	. 2 |- ( ph -> ( ch /\ th ) )
5	1, 4	jca 306	1 |- ( ph -> ( ps /\ ( ch /\ th ) ) )
