Theorem psdadd

Description: The derivative of a sum is the sum of the derivatives. (Contributed by SN, 12-Apr-2025)

Ref Expression
Hypotheses psdadd.s ⊢ 𝑆 = ( 𝐼 mPwSer 𝑅 )
psdadd.b ⊢ 𝐵 = ( Base ‘ 𝑆 )
psdadd.p ⊢ + = ( +g ‘ 𝑆 )
psdadd.r ⊢ ( 𝜑 → 𝑅 ∈ CMnd )
psdadd.x ⊢ ( 𝜑 → 𝑋 ∈ 𝐼 )
psdadd.f ⊢ ( 𝜑 → 𝐹 ∈ 𝐵 )
psdadd.g ⊢ ( 𝜑 → 𝐺 ∈ 𝐵 )
Assertion psdadd ( 𝜑 → ( ( ( 𝐼 mPSDer 𝑅 ) ‘ 𝑋 ) ‘ ( 𝐹 + 𝐺 ) ) = ( ( ( ( 𝐼 mPSDer 𝑅 ) ‘ 𝑋 ) ‘ 𝐹 ) + ( ( ( 𝐼 mPSDer 𝑅 ) ‘ 𝑋 ) ‘ 𝐺 ) ) )
